You do not set the trades on any time limit . It is governed by the price going up to the next line of the grid . So for every trade you will get a fixed % gain . When the price drops , the bot will make another buy . I have seen one of my trades take 1 minute take place ! i.e. bought at say 9 a.m. and sold at 9.01 a.m. XRP and Dot have both gone down so I have a few trades unfinished. All at different prices . The bot is waiting for the price to go up to the next line .
If you stop the bot , you do not have to sell unless you are going to use another coin . Like Simmo it is a learning curve for me .
