How to apply one set of settings per EA per MT4?

[Mario Lukačić]

Hi

I am running 20+ MT4 on various brokers, each of these MT4 run an EA with special settings (including symbol with suffix ). 

I managed to extract suffix, preset the various settings required for each EA, and save it into template file, now i run into the following issue:

When i load a chart using ChartOpen(), it opens my EA, but after template is applied with ChartApplyTemplate() it removes my EA completely.

Is there another way of doing this, importing custom chart settings into each EA ? We run one EA per Terminal only in addition to jfx. 

Each EA have different custom settings created from our database into a template file.

Thanks in advance

Seems you're doing something wrong.. Check your template is configured correctly, check errors at terminal's journal tab (you need to make term visible first). 

ChartApplyTemplate applies everything from a template including EA.

Even if i make it visible first, nothing changes, but interesting thing is that there is no errors in app, exception or Journal inside of TS. 

But if i right click on chart -> Template, and i select mine template and click it all works, it loads it with EA and all mine settings. See on image http://prntscr.com/kobcr3

I checked template, i even saved it from chart first, but that is not helping too.

This is from Journal in MT4 http://prntscr.com/kobcds

How can I help..?

There is NJ4X EA management API (see description here - https://1drv.ms/u/s!AqAmwEMj2h0umPFo08EWBGmc_HOsuA)

It is proven to run any EA in production mode using ChartOpen/ChartApplyTemplate methods.

It costs $500.

Not sure how you can help, but from API docs ChartApplyTemplate() remarks says "The Expert Advisor will be unloaded and will not be able to continue operating in case of successful loading of a new template to the chart it is attached to. ".

I already loaded EA with ChartOpen(), then i use ChartApplyTemplate() just to apply template to chart, and in case this success it removes EA.

This have no sense to me, why unload EA if you apply template ?

if (IsConnectedToTerminal())

{

                    //turn off symbols from MW

                    foreach (var symbol in Symbols) SymbolSelect(symbol, false);

                    long chartId = 0;

                    chartId = ChartOpen("EURUSD-", Timeframe.PERIOD_H4); // open chart after connection

                    if (chartId != 0)

                    {

                        // apply template to chart

                        ChartApplyTemplate(chartId, AccountNumber().ToString() + ".tpl");

                    }

                }

In case you apply new template to the chart it is obvious that old EA must be unloaded - I see no problem here. Please check details about ChartApplyTemplate MQL4 method here - https://docs.mql4.com/chart_operations/chartapplytemplate

Is there exists any other way to do this, because when i load EA i need to fill few Inputs before it can work properly, but as i can see this is impossible with this way i am using right now.

[Roman Gerasimenko]

..but template already contains all EA inputs. As far as I know there is no other method to start EA with custom parameters.
