Some very fast moving coins can sometimes result in a small loss due to slippage. I.e. the price hits target of 1%, but in the few seconds it takes the bot to place the sell trade, the price has fallen to less that 1% and a loss is incurred. A solution to this would be to place sell trades before they are needed, with the target price specified. They would need to be monitored every minute and adjusted (deleted and re-placed) if the target price lowers. This is probably a v3 thing.
