This is not something which you can control, typically these trades happen either when liquidity is less ( the pending orders) or if a big buy/sell order is placed which moves market for a few seconds.
As they say, there are things which you can control and things which you cannot. This is one of those which we cannot, and hence no point worrying about it.
If you are trading stocks, make sure to check the liquidity if you are trading biggish volumes.
On Nifty this happens very occasionally, but I guess the emkay global incident, there was one incident where Infy was down 10% and hence Nifty also moved down. Nothing is sacrosanct
TCS is highly liquid stock, then why does this happen in TCS?
I think we cannot blame liquidity, it happens as and when it happens, no choice, So we should’nt worry about such freak values. It happens once in a blue moon, I suppose.
