Comment on Order placement enhancements on Kite
If you want to enter a BO position at market, place a limit entry just above the current market price and it’ll execute like a market price, but will also protect you from any large impact costs. Market orders will execute at any available bid/offer and so may end up creating large impact costs.
As for BO for options, liquidity is always an issue, so BO would be tricky. The BO exit is always a market exit, and market orders aren’t allowed on stock options, again for liquidity concerns.
