I have been using profittrailer and gunbot with no problems at all. Earning good in bull market, not so good in bear market.
How long have you been using profitraile and gunbot now? And do they require you to pay for their apps? At what cost? I have seen some offering trading bots and asking for so much but in the end, they are all just scam bots. But I know for some facts that the trading bots are also being used by the exchange to make their volume higher.
