My strategy is so slow to test in JForex historical tester and there is a bug, please advise.

BUG:
Default instrument must be manually changed in the Visual JForex blocks and the strategy built again for each pair,. If using global variable set to true for default instrument and choosing a different pair other than the default in the Visual JForex blocks, the strategy will produce random entries all over the place. Is this a bug? Using the default currency works fine.

SUPER SLOW HISTORICAL TESTER
Do I need to use "tick" method of testing for accurate entries/exits and spreads? My strategy can enter/exit during a candle. It is painfully slow testing with ticks, is that normal? Maybe it is because when I first run a test for the last year the data has to first be downloaded? I maxed up the Java Heatmap and even after running a non-visual/non-optimized backtest for a year to collect the data, it is still extremely slow. I have a high spec PC setup. Maybe there is some unnecessary calls in my code? Please take a look

Hi,



This is a normal behavior, VJF is designed to trade on a given default instrument by this is not stopping to trade on more than one instrument.
When using more than a single instrument, the best practice is to avoid the use of "Default instrument" and call "Get historical candle with the needed instrument pair (frequently used with shift 1 to get full completed OHLC data)



Super slow: true this is because you're using many indicator blocks with the same inputs which is quite demanding in terms of resources. The update frequency itself is too high: every 10 sec the indicator should retrieve its output data (on 5mn period basis) and this 4 times in parallel. THis will slow down the flash interface (VJF) and requires more resources from the browser, the flash plugin etc ...
I've started some modifications on your file to optimize the way the strategy is built but I did not test it as I don't have a detailed description of the specifications. Please have a look and let me know in case you did not understand a certain logic / trigger / block

Cheers

Thank you for that, it helped for reference and in the meantime I came up with a similar solution through browsing the forums and some trial and error. I did as you shown in the template and removed duplicate calls of the indicator.

As I would like to run the strategy on separate instruments without coding them all into one strategy, I understand the ONLY way to do this is to rename the buy/sell variables, chose a different "default instrument" depending on the currency pair I will run it on and save the strategy as a different name, e.g. "My_Strategy_GBPUSD". Is this correct?

I read a reply you posted to someone who wanted to run their strategy on separate instruments and allow them to limit trades independently and you suggested by using "logical steps" as currently there is no feature to check open orders limit on a specific currency pair, as "open positions" takes into account all pairs. This would be a great feature to add in the future but for now I guess the "best" way is renaming the variables and saving a separate strategy for each instrument that I wish to trade.

Thank you for your.

Hi,


Unfortunately this is not the case anymore: It was possible to work this way before but we recently enhanced the "position amount" variable (number of open positions) to be able to retrieve all the opened positions on any instrument. So even if you use many strategy files, the use of position number condition will interfere across the strategies .
So I recommend you to use the logical triggers instead till we release the new block that will handle this feature in a more user friendly way.

Thanks
