Right, it's not useful at all then because the whole point of a BO is to save time but this, in fact, consumes more time if you have to modify all of these orders individually.
Well, irrespective of whether orders are sent from Watchlist or from charts, I'd think that their Order Management System would be the same, unless they actually found a way to resolve this issue altogether. They should at least allow us to quickly cancel & merge all of these orders into a single SL & TP in a couple of clicks.
Are you trading with Zerodha? Like I've said before, I've never used BO from any broker until now since RKSV are the first one that I'm working with, who offer SL-L entries for BO while other brokers I've tried only seem to offer BO's with simple Limit entries, which I don't like. Right, it's terrible having to pay several times the brokerage you were actually supposed to pay but I'm not really sure if this issue is completely unsolvable; like I've said, if they can't stop formation of multiple SL's & TP's then they could perhaps offer an option to right-click that stock in the Position Book to cancel & merge all such SL's & TP's into a single SL & TP quickly, instead of expecting day-traders to waste so much time in modifying orders as well as pay several times the brokerage. In case of commodities, at least there are lots, which can only be broken into a limited number of parts but imagine putting orders of similar monetary value in stocks, which might be broken into numerous chunks; just to illustrate the point, today, Apollotyre had an average volume of 18914 shares PER MINUTE & 315 shares PER SECOND, & mine was a very small order of merely 90 shares, which got broken up into 5 chunks, so just imagine what it could potentially do to a substantially large order, which might get executed in many dozens of little chunks, that's what I'm most concerned with, & I don't think I can dare to put in larger orders if they can't solve this issue.
