Comment on Trading Q&A
As brokers we only provide clients a platform to place orders. Order matching and subsequent execution based on available bid/ask prices happens at the Exchange end. The OMS that we use for sending out orders is from Thomson Reuters who is probably the biggest in the context of the Indian markets. There can’t be latency in the prices that show up, cos if it did, it would have affected a larger set of our clients. Slippage is the only explanation that I can think of, however since you always have the option of placing a limit order, it’s best to place one.
