Answer
No it is not, spot future arbitrage will open position with the same size in spot market and in future market. that -43 usd loss is from beginning of the bot, meanwhile the 11 usd profit in spot market is just today profit. Overall, the profit and loss since beginning is really close to 0 (depend on your price gap when creating the bot). As long as you dont touch the bot (withdraw/add margin) , the overall value in USDT will still the same, you will gain profit and loss only from funding fee, and some fluctuating unrealized profit from real time price gap.
