the long-awaited update!
- Added the ability to disable the trading panel
- Added the ability to restrict purchase/sale transactions 
- Fixed a bug that allowed trading on the night from Sunday to Monday
- The main thing: added the ability to use the One chart function! This will allow you not only to trade from the heart, but also to test the Expert Advisor in multi-currency mode! 
Please read the instructions for setting up this function carefully!

For those who are here: if you did not have time to buy at this price, hurry up. tomorrow the price will be $399!

this is called slippage. Therefore, you need a good broker so that the execution of transactions is fast and without delay. When testing, we cannot predict delays and slippage. If in the end you make a profit, then everything is fine.

Hello Marat,

as I think the ability to use multi currency is very useful, I just tested it with V1.6. In the set file the possible test operations are single - tick and multi - on timer.

I used just the pair EURUSD in both single and multi currency (so yet only one pair in multi currency, too). The trade simulation results are almost identical. However even with just one pair, the multi currency mode takes much more time then the single currency mode.

Can you share why the multi currency mode seems to be different and not use the efficient tick model, too? What does "on timer" really mean?

I would think as many other multi currency EAs perform the same way whether one uses 1 or several symbols, the performance per symbol could be the same when the different currencies do not influence each other (seperate entry points and TP or SL events for all pairs - they are treated independently in the EA).

Thank you.

Hi.

good question. When testing in the multi-currency mode, the tick data is read by a timer. that is, once at a certain time, the adviser checks whether there is a signal to open a deal. Apparently, the feature of the MT5 tester makes this process very long. When testing in the single mode, the EA processes each tick and checks if there is a signal to open a deal.

I deliberately left both modes in order to leave the opportunity to optimize the adviser if you want.

There is no other way to process ticks, since the EA works not on closed bars, but on tick data.

Thank you Marat. Not being a programmer, I admit to still not fully understand the timer concept with MQL 5. I would have thought even with multi currency setup, each FX pair would be treated same way as in a single currency setup. The multicurrency feature is very useful so the longer processing time is accepted.

I noticed one more reason why a multipcurrency operation makes sense, this is the CPU load that the MT terminals cause with 12 different chart windows. I have a powerful VPS server but that machine showed quite a noticeable load with 12 charts. Haven't tested V1.6 on VPS yet but hope the CPU load will be reduced if only one chart is used. 

Fixed lot 0.01, Using ticks imported from TDS, 2012~2022.

Lovely!

Hello Marat,

USDJPY got doubled up.

Should one of them be USDCHF?

Yes that's right. ] wrong.

After replacing the doubled USDJPY with USDCHF. fixed lot 0.01, 2012~2022

Thank you!

if it's not difficult for you, please post a full report

Performance of individual pairs

I wanted to do a test in auto lot mode since 2010, but in 5 years the EA reaches the maximum lot.

Do you ahve a set file for the "onechart" setup for icmarkets, please?

Thank you
