1) so lets assume i buy 100 shares of sbi at 100 and sbi surges to 110 and i want to close my trade , now will my trade close and credited immediately (like in forex ) or will it wait for buy order to match my trade .if it waits for match the order than what if sbi retracts to 106 ,where will my trade close 110 or 106 ??

2) do online stock brokers like kotak,icic,sbi etc provide leverage ( like in forex ) ,if they do how much? whats the max leverage provided by which broker?

Hope you understood my questions ,thankyou
