Comment on Streak just got a whole lot better
Though options have time decay, backtest can be performed on whichever data available till the date. For weekly expiries in both nifty and banknifty, same strategies are to be applied on multiple strike prices. If streak allows nifty/banknifty options, definitely the strategies can be backtested for at least a day or two and that too can be tested for different strike prices; which is enough to validate strategy for algo trading.
