@roar I will try again with max 3 symbols and see if outcomes are still unexplicable.

@roar Did you use the "set market" block in that proyect in which you ran that backtest that you sent? and if you used it how many pairs did you put into the block?

@roar I checked for RAM during the optimization and it had plenty to go on still, and I test the bots only on a percandle basis, this time being 4 Hour candles.

@l-andorrà I already made a Bug report about that block. providing evidence on backtest about the error. However I am doing further tests to see if I can find where things go nuts.

Hello, I have just started to use the set current market block, so take this bug finding with a grain of salt. This is the proyect that I have used it inhttps://fxdreema.com/shared/a3XQcZs7. I have used the block so that I can optimize finding the common set of parameters that maximizes profit in a list of pairs that i have given the block as a string input, so as I understand: the bot will run through this list (matterless of the current symbol chosen on MT5 Backtester/Optimization) and will make a portfolio of the list of pairs and run through it.

However I have noticed that:

1. results will change based on the symbol selected in the backtester.
2. Here I attach a optimization on all marketwatch symbols (all 10 pairs are in marketwatch) and observe that depending on the pair returns DO change. (image 2) ![Optimizations all pairs image 2 ]
3. results from the backtest when selecting that pair (for example USDCADMT5) will often differ from the one in the previous image![Single Selection USDCADMT5](.

That pretty much is everything I've got so far. I think it IS a bug, however due to simple ignorance I could be using the block in a wrong manner.
Please FxDreema, hopefully you can read this.

P.S. I know you are a single person with this whole project and your platform is hands on the best I have found ever. Keep the awesome work.

I've had exactly the same bug, whenever I change the pair inside settings (irrelevant of wether it is in the block list or not), it will change the results on the backtest. And the change is incredibly random, seldom have I backtested and the same result would be as expected. However I have not found it to be evidence of commisions/ SWAP charges, it severely changes trades.

I want to be able to automatically export the Report that you can save after a backtest (the HTML one that opens on the browser) after it has passed certain parameters, I look for this so that i can merge bots and create a portfolio.

It's ok, I can read code (it takes me a lot of time), and touching the .ini files get me in no trouble. I have already learned how to make it it run from the CMD (Windows), however I am looking for a way to put them inside the EA, so I can produce Reports enough to make the tests.

The chart is the balance chart, however i am actively looking for a way for it to store that same report in the link as a HTML file inside the code of the EA

Hi, I'm trying to make the EA store a HTML detailed report after each pass has succefully achieved a minimun profit, however i cannot find the command in MQL4 to achieve this.

I know you can do it from the .ini files, but it won't happen after each optimization pass, only after a backtest.

Can someone throw some light here please?
