Fixing dual problems Meta Trader 5 EA

Hello, my budget 30$

I have a MetaTrader 5 trading expert that I use on the same VPS on three different brokers, and all brokers have the same time server.

The first problem:

Is that the expert advisor has a sub-account and a chart panel show the required information. For example, if I enter $800 into the sub-account and the expert advisor earns $250, the sub-account becomes $1050 on panel. When I close the platform and reopen it, the account reverts to $800, even though the expert advisor uses the gvariables.dat file for storage. This problem is common to all brokers.

The second problem:

The first broker works without problems, but the other two brokers have a problem, which is if the trade does not reach the take profi or stop loss, for example, if the closing time is at 20:00, sometimes the trade closes and sometimes it does not close, but most of the time it does not close and remains open.

The expert trades on the (( Multi Simble system )), which uses eight symbols and has two engines. Void OnTick and Void OnTimer In the workplace, use OnTimer and currently, I am insist about using (( Void OnTimer ))

I want to fix both problems.
