Dies anyone know where to find trading software that works with exchange api?
I tried googling without luck but maybe i don't know the right terminology.
What I want to do is for example put in a limit futures order to buy at 19500 with a stop loss at 19000, but I want to program it so if the price goes above 20500 it will automatically change my stop loss to 20000, to prevent loosing profits if the price goes down.
Is it possible to do this on any exchange?
I thought about making a small app to do it with api's but maybe it already exists.
Thanks in advance for any help.
Basically, what you want is a trailing stop loss from what I can understand, this is possible in a few exchanges itself. As far as I know, Binance does provide this solution, you can put a trailing stop loss on Binance by setting the Gap price from the high of that very rally, which means if you put the order of 19500 and it is executed and you put a trailing stop loss of 5% so now if the price reaches 20500 your stop loss will get changed to somewhere around 19480. Similarly now if the price comes down for a bit and then again breaches 20k mark to reach 22k, your stop loss will now become around 21k. So this will be carried on until it drops 5% from the high of that rally. You can refer to this guide to understand the concept:
