Sometimes the order price of buy / sell changes after a few seconds for the executed orders . Today the buy price at 65.00 changed to 65.90 for one lot 11200 pe option in the order book after a few seconds. This took the buy price to near the top of the candle wick.
And again for one lot 11100 ce option the sell price changed from 94.60 to 86.95 in the order book after a few seconds. This took the sell price to near the bottom of the candle wick.
Why does the change in buy sell price take place? Once the buy/sell price confirmation comes from the exchange it should not change again.
Any other traders facing this issue ?
