Hi all,
I didn´t use that funcionality for a while, but before I could add several instruments in the ProBacktest window and the results for each of the selected instruments appeared together in a separate window. Now when I try that there is no new window appearing and it doesn´t seem to do anything else than the backtest of the instrument in the main graph, ignoring the rest of instruments I added in the tabs of the ProOrder Backtest window
Is this working different or it just doesn´t work anymore??
Cheers
It seems to be working different as we now have a ‘Multi-Results Table’ showing multi results from selected Timeframes, but not from more than 1 Instrument.
Please post a screenshot of how (using which button etc) you add > 1 Instrument to probacktest and I’ll replicate your method to see what I get.
Hi Grahal,
In the picture you can see where we can add several instruments for the same backtest, one tab for instrument. And before when I executed this backtest with several instruments a new window appeared with the resulst for each instrument. Now it doesn´t, doesn´t seem to do anything but the usual instrument-on-graph backtest no matter how many instruments you add in these tabs.
I didn´t know about the “Multi-Results Table” for different TFs you comment.. Where is it or how can I run it?
Thanks

Was it backtests (not optimisation?) you did with several instruments at same time?
Was the new window you speak of a ‘Detailed Report’ and I guess you must have had separate equity curves as well as separate Detailed Reports for each instrument

The Multi-Results Table appears as a default when you run optimisation using different Timeframes.
The multi resuts beng one set of opti-results (variable values) for each Timeframe.
?
but not from more than 1 Instrument.
Correction… the multi-Table does show results from optimisation of more than 1 instrument, but we can optimise only one instrument at a time.

You could do both, just backtest or optimisation, for all the instruments together. About the window that appeared before I realized I have a picture of it from some time ago, it´s the first image attached. It was ONE window for all the instruments with the main data. The image is just a backtest, in case you did a optimisation you could see also the results of the variables for each instrument. Also you could select each of the rows/instruments in the window and the graph/detailed report of that instrument appeared as usual. This function has some issues but was a very useful, I used quite a lot and I hope it hasn´t go missing now.

Sorry Grahal, I don´t follow you, can you send me some picture of it?. I tried to do an optimization in a system with different Timeframes in its code and the results where as always. I did notice now something new though: if I do consecutive/different optimisations the results no desappear as before but are kept in the “optimisation window” in a different “set of data” that you can expand/contract as in the second image attached. But they are different/consecutive optimisations I did, not different Timeframes as you mention.
Sorry I was referring to Timeframe of the Chart – named as Timescale Resolution.
The multi-Table is very similar to what you show above except that Instrument No 2 (which then replaces Instrument No 1) is added / selected using the drop-down to the left of Timescale Resolution.
Ok, if I understand you correctly now you are referring to the new feature as in my 2nd attached image, where you can do different/consecutive optimisations and keep all the results in the same table/window so you can compare them. Is that right?
But this is not only MultiTimeFrame related as you mentioned before, it can be used for any kind of diferent optimisations: different variables, different instruments, different timeframes…. you can do all these different optimisations and all them will appear together in that table/window to compare.
It´s an interesting and probably useful new feature, but now I just wanted the old multiinstrument feature because with it I could get similar analysis much easier as I didn´t have to execute one different opitimisation per instrument as here
Yes use of the multi-Table is as you describe above.
I can’t help wondering if the limit of ‘1 opti at a time’ has been introduced to limit opti-load on PRT servers?
I would have tried the multi-instrument opti, but I never noticed that + button! 🙂
- Did, for example, 3 optis run in parallel and 3 sets of results appear simultaneously?
- Or
did No 1 algo run fully, then No 2 algo start and run fully, then no 3 etc??

You are probably right, it sounds like the kind of thing they would do. It´s a shame though, for me it was a very useful feature

I think they runned in parallel, because during the calculations a window appeared with the % progress for each instrument, and they looked like they runned all at the same time.
