Maximum Drawdown - MQL VPS

 
Hi, We are running an EA with MQL.com VPN. When we generate the detailed report in our desktop Mt4 then it's not calculating the correct draw down. It always shows the same drawdown which it was at the start of EA running. Now it's more than 10 days and we know that floating amount was very big during trades running but it's not updating the Max drawdown. Could anyone help here how can we get the maximum drawdown correctly. Is there any indicator available or it it due to that EA is running with VPS?
