I have never tried using Grid before but most of the bots on telegram communities are not profitable after trading for more than 2 months. This means that the bots will soon become outdated and unable to update good market data, so they constantly trade errors. I used to join 2000 $ in trading pool traded by TCVN bot and now I have lost more than 500 $. So, do not trust the trading bots in community channels too much, use your knowledge to trade better.
Trading bots cannot be trusted at all, this is a mistake. Nobody will share with you a working bot that brings money, it makes no sense.
They would make money on it themselves and would not share anything, because you can easily analyze and copy the strategy by creating your own bot.
