Your polo graph doen't match your settings. You are looking at 15 min candles, but you have set 5 minut periods. Also, EMAs are little low, generally they are set 4/2 hours. You have 80/40 minutes. If you are after trades, and having BB your buying strat, setting it to 25 will take a while to get monero, or doge (doge is a completely other can of worms, check its graph) or bitcoincash bought. so, there's your reasons for no trades. You are looking at a different picture than the bot, and you are set very conservatively in bearish market ... You need to find a slightly climbing pair, set the candles to the same you have on your strat, and see if it at all reaches your low BB. If not, set accordingly. With pairs like these and the settings you have, you can't expect the bot to buy. It does not perform miracles ...
