Programming language: algoZ

April 23, 2013

Beginners, don’t worry if you don’t understand when you read this manual. We will explain how to code your technical analysis strategy in the “Code your strategy” section.

Programming language

This blog contains short examples that demonstrate how to perform common, basic tasks such as identifying securities within a specific price range, increase in volatility, crossing over of an indicator, and so forth. You can cut and paste many of these examples right into the NEST Pulse’s programming area on Zerodha Trader.

Also this blog contains a reference of functions, properties, and constants supported by the NEST Pulse language as well as hands-on trading system examples. This method of organization allows the beginning programmer to see results immediately while learning at his or her own pace. NEST Pulse is the engine that drives the scripting language in your trading software. It is a non-procedural scientific vector programming language that was designed specifically for developing trading systems. A script is simply a set of instructions that tells the NEST Pulse engine to do something useful, such as provide an alert when the price of one stock reaches a new high, crosses over a moving average, or drops by a certain percentage. There are many uses.

Introduction: Important Concepts

NEST Pulse is a powerful and versatile programming language for traders.

The language provides the framework required to build sophisticated trading programs piece by piece without extensive training or programming experience.

The following script is a very simple example that identifies markets that are trading higher than the opening price:

LAST > OPEN

It almost goes without saying that the purpose of this script is to identify when the last price is trading higher than the open price. It is nearly as plain as English language.

Just as a spoken language gives you many ways to express each idea, the NEST Pulse programming language provides a wide variety of ways to program a Trading System. Scripts can be very simple as just shown or extremely complex, consisting of many hundreds of lines of instructions. But for most systems, scripts usually consist of just a few lines of code.

The examples outlined in the first section of this blog are relatively short and simple but provide a foundation for the development of more complex scripts.

Boolean Logic

The scripts shown in this first section may be linked together using Boolean logic just by adding the AND or the OR keyword, for example:

Script 1 evaluates to true when the last price is higher than the open price:

LAST > OPEN

Script 2 evaluates to true when volume is two times the previous day’s volume:

VOLUME >REF(VOLUME, 1) * 2

You can aggregate scripts so that your script returns results for securities that are higher than the open and with the volume two times the previous volume:

LAST > OPEN AND VOLUME >REF(VOLUME, 1) * 2

Likewise, you can change the AND into an OR to find securities that are either trading higher than the open or have a volume two times the previous volume:

LAST > OPEN OR VOLUME >REF(VOLUME, 1) * 2

Once again, the instructions are nearly is plain as the English language. The use of Boolean logic with the AND and OR keywords is a very important concept that is used extensively by the NEST Pulse programming language.

Program Structure

It does not matter if your code is all on a single line or on multiple lines. It is often easier to read a script where the code is broken into multiple lines. The following script will work exactly as the previous example, but is somewhat easier to read:

LAST > OPEN OR VOLUME >REF(VOLUME, 1) * 2

It is good practice to structure your scripts to make them as intuitive as possible for future reference. In some cases it may be useful to add comments to a very complex script. A comment is used to include explanatory remarks in a script.

Whenever the pound sign is placed at the beginning of a line, the script will ignore the words that follow. The words will only serve as a comment or note to make the script more understandable:

# Evaluates to true when the last price is higher than the open or the volume is 2 X’s the previous volume:

LAST > OPEN OR
VOLUME >REF(VOLUME, 1) * 2

The script runs just as it did before with the only difference being that you can more easily understand the design and purpose of the script.

Functions

The NEST Pulse language provides many built-in functions that make programming easier. When functions are built into the core of a programming language they are referred to as primitives. The TREND function is one example:

TREND(CLOSE, 30) = UP

In this example, the TREND function tells NEST Pulse to identify trades where the closing price is in a 30-day uptrend.

The values that are contained inside a function (such as the REF function or the TREND function) are called arguments. Here there are two arguments in the TREND function. Argument #1 is the closing price, and argument #2 is 30, as in “30 days” or “30 periods”

Only one of two things will occur if you use a function incorrectly will automatically fix the problem and the script will still run, or NEST Pulse will report an error, tell you what’s wrong with the script, and then allow you to fix the problem and try again.

In other words, user input errors will never cause NEST Pulse to break or return erroneous results without first warning you about a potential problem.

Let’s take CLOSE out of the TREND function and then try to run the script again:

TREND(30) = UP

The following error occurs:

Error: argument of “TREND” function not optional.

We are given the option to fix the script and try again.

Vector Programming

Vector programming languages (also known as array or multidimensional languages) generalize operations on scalars to apply transparently to vectors, matrices, and higher dimensional arrays.

The fundamental idea behind vector programming is that operations apply at once to an entire set of values (a vector or field). This allows you to think and operate on whole aggregates of data, without having to resort to explicit loops of individual scalar operations.

As an example, to calculate a simple moving average based on the median price of a stock over 30 days, in a traditional programming language such as BASIC you would be required to write a program similar to this:

For each symbol
    For bar = 30 to max
        Average = 0
        For n = bar - 30 to bar
            median = (CLOSE + OPEN) / 2
            Average = Average + median
        Next
        MedianAverages(bar) = Average / 30
    Next bar
Next symbol

Nine to ten lines of code would be required to create the “MedianAverages†vector. But with NEST Pulse, you can effectively accomplish the same thing using only one line:

SET MedianAverage = SimpleMovingAverage((CLOSE + OPEN) / 2, 30)

And now MedianAverage is actually a new vector that contains the 30-period simple moving average of the median price of the stock at each point.

It is not uncommon to find array programming language “one-liners” that require more than a couple of pages of BASIC, Java or C++ code.

The REF Function

At this point you may be wondering what “REF” and “TREND” are. These are two of the very useful primitives that are built into the NEST Pulse language.

The REF function is used whenever you want to reference a value at any specific point in a vector. Assume the MedianAverage vector contains the average median price of a stock. In order to access a particular element in the vector using a traditional programming language, you would write:

SET A = MedianAverage[n]

Using NestPulse you would write:

SET A = REF(MedianAverage, n)

The main difference other than a variation in syntax is that traditional languages reference the points in a vector starting from the beginning, or 0 if the vectors are zero-based. NEST Pulse on the other hand references values backwards, from the end. This is most convenient since the purpose of NEST Pulse is of course, to develop trading systems. It is always the last, most recent value that is of most importance. To get the most recent value in the MedianAverage vector we could write:

SET A = REF(MedianAverage, 0)

Which is the same as not using the REF function at all. Therefore the preferred way to get the last value (the most recent value) in a vector is to simply write:

SET A = MedianAverage

The last value of a vector is always assumed when the REF function is absent.

To get the value as of one bar ago, we would write:

SET A = REF(MedianAverage, 1)

Or two bars ago:

SET A = REF(MedianAverage, 2)

The TREND Function

Stock traders often refer to “trending” as a state when the price of a stock has been increasing (up-trending) or decreasing (down-trending) for several days, weeks, months, or years. The typical investor or trader would avoid opening a new long position of a stock that has been in a downtrend for many months.

NEST Pulse provides a primitive function aptly named TREND especially for detecting trends in stock price, volume, or indicators: TREND(CLOSE, 30) = UP

This tells NEST Pulse to identify trades where the closing price is in a 30-day uptrend. Similarly, you could also use the TREND function to find trends in volume or technical indicators:

# The volume has been in a downtrend for at least 10 days:

TREND(VOLUME, 10) = DOWN

# The 14-day CMO indicator has been up-trending for at least 20 days:

TREND(CMO(CLOSE, 14), 20) = UP

It is useful to use the TREND function for confirming a trading system signal.

Suppose we have a trading system that buys when the close price crosses above a 20-day Simple Moving Average. The script may look similar to this:

# Gives a buy signal when the close price crosses above the 20-day SMA

CROSSOVER(CLOSE, SimpleMovingAverage(CLOSE, 20)) = TRUE

It would be helpful in this case to narrow the script down to only the securities that have been in a general downtrend for some time. We can add the following line of code to achieve this:

AND TREND(CLOSE, 40) = DOWN

TREND tells us if a vector has been trending upwards, downwards, or sideways, but does not tell us the degree of which it has been trending. We can use the REF function in order to determine the range in which the data has been trending. To find the change from the most current price and the price 40 bars ago, we could write:

SET A = LAST - REF(CLOSE, 40)

Price Gaps and Volatility

Although the TREND function can be used for identifying trends and the REF function can be used for determining the degree in which a stock has moved, it is often very useful to identify gaps in prices and extreme volume changes, which may be early indications of a change in trend.

We can achieve this by writing:

# Returns true when the price has gapped up

LOW >REF(HIGH, 1)

Or:

# Returns true when the price has gapped down

HIGH <REF(LOW, 1)

You can further specify a minimum percentage for the price gap:

# Returns true when the price has gapped up at least 1%

LOW >REF(HIGH, 1) * 1.01

And with a slight variation we can also the volume is either up or down by a large margin:

# the volume is up 1000%

VOLUME >REF(VOLUME, 1) * 10

Or by the average volume:

# the volume is up 1000% over average volume

VOLUME >SimpleMovingAverage(VOLUME, 30) * 10

We can also measure volatility in price or volume by using any one of the built-in technical indicators such as the Volume Oscillator, Chaikin Volatility Index, Coefficient of Determination,Price Rate of Change, Historical Volatility Index, etc.

    Lot of thanks for your splendid initiative.Hope the blog continues to teach and help to develop trading system of the members.I tried my hand to write a few programs
    which produced good result until I was stucked in the following program for BUY or SELL Exit:

    VOLUME( OR (REF VOLUME,1) OR(REF VOLUME,2) OR(REF VOLUME,3) OR( REF VOLUME,4) OR (REF VOLUME,5) OR REF VOLUME,6)>SIMPLE MOVING AVRRAGE(VOLUME,20)*10

    When I put it to back test NEST TRADER error was ” Back Test Script Error:Error:Undefined Function “VOLUME” ”
    Pls help me out.

    Debjani

    • Nithin Kamath says:

      Debjani this would be the code:

      SET V = VOLUME
      (V > SMA (V,20) *10) OR (REF (V,1) > SMA (V, 20)*10) OR (REF (V, 2) > SMA (V, 20)*10) OR (REF(V, 3) > SMA(V, 20)*10) OR (REF (V, 4) > SMA (V, 20)*10) OR (REF (V, 5) > SMA (V, 20) *10) OR (REF (V, 6) > SMA (V, 20)*10)

    Hello

    I would like to code a strategy for for Nifty futures. Kindly help.

    If Last Traded Price of Ambuja Cem > Current Price then A = 10
    else A = -10

    If Last Traded Price of Sun Pharma > Current Price then A = 20
    else A = -20

    If Last Traded Price of RCom > Current Price then A = 30
    else A = -30

    If Last Traded Price of Yes Bank > Current Price then A = 40
    else A = -40

    Sum = A + B + C + D

    IF Sum > 60 Buy NIfty futures and if Sum < 60 Sell Nifty Futures.

    Stop loss =

    Nifty Low + 5 % Nifty Low If Sum < 60
    Nifth High – 5% Nifty High If Sum > 60

    And is there any code to get VWAP for shares.

    Hi Team,
    I’m using Renko Chart type.
    Can you please give me the equation for the following
    SEll if 2 renko red bars are formed ,exit when one green bar is formed
    BUY if 2 renko green bars are formed ,exit when one red bar is formed

  6. Ravikumar says:

    Hi,
    Can you help me to get this strategy

    I’ve the following Indicator
    EMA(CLOSE,14)
    SMA(CLOSE,40)

    SELL
    1. Angle of EMA(CLOSE,14) is less than 0 ‘
    2. EMA(CLOSE,14) crosses SMA(CLOSE,40) from up
    EXIT
    Angle of EMA(close,14) gets near 0′

    And vice versa for Buy Call

  7. Ravikumar says:

    Hi
    How can i find the slope for SMA with 30 periods .

    Thanks

    • Hanan says:

      Ravi, could you please elaborate on your question? If I understand you right, we don’t have a Slope indicator on Zerodha Trader for SMA but there are loads of other indicators that you can try out.

      • Ravikumar says:

        Can you help me for this.
        Make a sell call, WHEN SMA (30) is decreasing and make buy when SMA(30) is increasing
        Thanks

  8. Varughese K Eappen says:

    Hi,
    I want to code this :Buy when MACD line crosses above Signal line and MACD above zero and RSI>50

    • Hanan says:

      Here’s the answer from the Nest Plus team…

      Please find the algoZ codes based on the logic provided.

      (MACD(13, 26, 9,EXPONENTIAL) > MACDSignal(13,26, 9, EXPONENTIAL)) and (MACD(13, 26, 9,EXPONENTIAL) > 0) and (Rsi(Close, 14) > 50)

      Please Back test them to assess the performance before applying live.

  9. Ashish says:

    Hello team, I’m unable to get EMA function under moving average. there are other VMA,WMA etc. but unable to see EMA. What could be the reason behind this?

    • Ashish, EMA is exponential moving average, so yes you can use that, it might have been missed in the above post.

      • Ashish says:

        Thanks Nithin. I had another query on backtesting. Is it possible to backtest the strategy including stop loss order. Currently backtesting result shows the overall profit and loss but I would like get the result by taking stoploss order consideration so that overall loss will get reduced.

        • Ashish,

          In your exit script, have an OR condition separating your Target and your Stop. The only thing with this is that you can’t have stop as a numerical value, it will again have to be a technical analysis condition.

          Cheers,

  10. Ashish says:

    Hello Nithin, I just tried that when I’m going live with my strategy, Bracket order and trailing tick is disabled. How to enable those parameters ?

    • Hanan says:

      Bracket orders and trailing stop losses are not yet available on ZT. This will be made available on the new release of ZT which we expect to come about within the next month or so.

    Hi,
    Can you please help me code the following condition:

    Chart type: intraday
    Candle duration: 15 mins

    Condition

    That particular has made a high which is equal to the days high (double top) or the script has made a new high which is within the range 0.2% of the days high on the lower side and that particular candle hasn’t broken the days high in that 15 minute duration.

    Like if days high is 100, the candle makes a high of 100 or somewhere between 99.80 to 100 that is 0.2% and the candle does not break the high in that 15 min duration.

    I am basically looking for a code to detect double top pattern with 0.2% margin of error on the lower side while making the second top.

    Hope I explained properly.

    hello nithin sir,
    i am newly start to learn “tradescript language(algoZ)”.i tried to back taste ‘IDEA’ with simple code. i choose :– periodicity=day,barinterval=1, months=50.(i am not write any code in exit long/short script)
    buy scripte code -OPEN=LOW
    SELL script code -open=high
    “it means that if open price equal to low price a buy signal is generated and if open price is equal to high price a sell signal is generated”
    some signal are generated,buy signal when o=l and sell signal when o=h, but i observed that some day also where open price equal to low price and where open =high price there is no signal is generated.
    following are some day when no signal is generated while all condition are satisfied:-
    6/12/2016-open=low
    2/6/2016-open =low
    7/4/2016-open =high
    above are the date(dd/mm/yy) when condition is satisfied but buy/sell signal is not generated,there are many days which have same issue but problem is data box not shown date on many candle bar(chart generated by back testing) so i write only some dates only.i am also confirm from historical data of NSE.
    sir kindly guide me that there is any mistake in my code and cross chek if it is possible.
