Both your wallet and your current profit values take into account all money on your exchange.
If you have other coins in your exchange (eg: hodl coins, coins you are holding manually)
If those coins decrease in value, both your wallet and current profit will decrease.
This is not due to bot results, but purely because you don't have a separate account for your bot to trade on.
Another option is your open positions
The bot exchanges your basecoin to other coins to make trades.
If the market for this coin drops on one of those open positions,
then this trade will temporarily be in red (loss), untill the bot is able to sell it again in green.
This will decrease both your wallet value and current profit value.
Don't worry, just wait for the market to increase again and this position will be sold with profits again.
