Bot appearts to have stopped following the code logic

I have my bot on cloud instance ID122928. It has been working fine on H4 time frame and usaully place d a trade onec in 2 weeks. However on 18th Dec it violated the code logic and placed >1000 trades in  arounf 40mins and blown my acocunt on spread and commissisons. Ctrader interface doesn't provide any server execution logs so I have no idea what went wrong and if it was something I could've accounted for in my code. Or was it Calgo glitch? Can you review from your end and help me get to the root cause?
