Its possible yes but really hard within the same bot. You can offcourse run a long bot and a short bot on the same coin and use hedge mode on the exchange.
I have a short version but i havent touched it for a long time so its not in sync with the long version. Maybe i share it when i have time to update it.
The SMA cross signal can be sent from tradingview or you can edit the bot sources.
Some other interessting signals are the “technical ratings” on tradingview. You can sent an alert to start based on a timeframe and buy, strong buy, sell, strong sell.
But it is not easy to get the timing perfect.
