This is your MT4 terminal Journal tab, don't confuse it with your MQL5 VPS server Journal.
In order to check if your EA is properly synchronized with your MQL5 VPS server, you must right click on the MQL5 VPS server in the Navigator
window >> Journals.
If you don't see the 1 EA message, you should synchronize again your local MT4 chart (with your EA attached to it and the AutoTrading button
clicked), with your MQL5 VPS server.
Yes you can, but its highly unadvisable because you will be interfering with EA's risk and money management, unless you use a low risk strategy
and you know what you are doing.
There is not any custom tools on mobile sorry (EA is the custom tool) ...If you are talking about trading manually ... so
... it should be your choice ...
But please note that "this guy" (your EA) is never sleeping because of VPS ... (it may be the contradiction with it).
For peace of mind you could always have a pending
order in a test EA which would only be created at a time after you have synched your EA with the VPS.
Then you can actually see the VPS has done as instructed, at least in the case of opening the pending order...then just cancel the order
