I think your asking about an "what if" order or a special instruction order.. I only have seen a few brokers in the stock market with those functions.. But not anything like that in Cryptos yet.. But basically you would write an order in ninja trader, that follows a script, and if your buy order fills durring the night the platform would automatically write a sell at your set higher price.. .. but we dont have that.. all we can do is make sure we get an alert when we buy and then get up and write in a sell order.. I had 59 orders execute yesterday and last night.. wow im busy when the market pulls back
