Now, the problem is, price actually never really reached to 243.25. The low price at 9:59 is 243.6 when I checked the real time data as well as the historical data for yesterday (26/Jun/19). You can check this yourself in kite or historical data API. This trade turned out to be a loser even though it was a hugely winning trade just because of this pre-mature SL hit. Either the candle data is wrong or more seriously, there is a problem with the order management system. I think this is the third time happening to me. Earlier, when this happened, the price volatility was too much. So, I thought, probably, some technical glitch. But, in this example, the price movements were very quiet. So, I don't understand what is happening. Can someone please look into this on priority as I think this is critical issue and losing money due to problematic execution of orders is not an option for any real trader? Thanks.
