Quick timing issue conversion

Hi everyone, I am hoping that you would be able to help me with possibly an easy fix. I have exhausted all avenues to try and optimise a 3 min US100 / USTEC and convert from line script to MQL5 so I can automate through MT5. 

The trades are not correlating and there is a clear consistent discrepancy of approximately 123 minutes between a significant number of trades when comparing the same time period. I really hope that someone is able to fix this, it seems like a structural issue in the code I have been unable to find to correct. Please can someone come forward to help solve this issue. Thank you in advance
