Do most firms take away buying power when you place a buy/sell stop order or when the order is actually executed? Lets say a stock is trading in a range and I want to go short if it breaks bellow the range or go long if it breaks above the range. I want to put in a buy stop and a sell stop at the same time and let it play out which one gets triggered. Now if i was buying $10,000 worth of shares, would I need $20,000 in buying power to place the 2 stops or will they only take away from buying power when the one of the stops is hit and I enter the trade? Right now i would need to have enough BP to cover both the stops. Is this true for everyone?
