Blessing Multipair EA

My first thread in this forum, I am so excited...

The idea for this EA started in another thread:
https://www.forexfactory.com/showthread.php?t=792598

Therefore this EA is based on the wonderful EA called “Blessing 3 v3.9.6.09”.

The idea to try to build a multipair version came up in the above mentioned thread. After some brainstorming I began to like the idea. Though Blessing and multipair is kind of a contradiction. Blessing has so many parameters to finetune the EA exactly to your pair to trade, the time frame, your risk and and and.
But anyway it might be worth a try to find some “global settings” that work well for all pairs. Just adjusted to the time frame and other global parameters (risk, broker and and and).

What did I basically do?

  1. I took the latest source code from the original thread (“Blessing 3 v3.9.6.13”).
  2. … cleaned it from almost all display output
  3. … introduced a big struct that holds the variables for the pair to trade
  4. The start function is running a long “for to” loop over an array of the structs for the pairs to trade
  5. I took out the hedge function
  6. only one and fixed magical number to be able to monitor the trades via a dashboard
  7. ...moved the main part of the holiday check to the beginning of the start function


Sounds simple but gave me some headache as the debug options for bugfixing in MT4 are really poor, compared to a “real” compiler.
I can only perform backtesting with one pair at a time, which is not enough for a multipair EA. In realtime mode I can see whether it is working, but it is difficult to see if it is working in the right way.
Enough words written: please take a look at the code and feel free to give feedback. There are for sure still many open points that I would love to discuss here in this thread.
Especially when it comes to global settings (e.g. number of open trades) that might need to be moved into the struct.
And please play around with different set-files to see which settings come close to “one size fits all” (thx Grand Wazoo). As a good starting point I can recommend the collection from Richard96816, that can be found in this post:

https://www.forexfactory.com/showthr...4#post12628494
(thanks a million, Richard!)

→ for backtesting, the setting for „Use the 28 default pairs“ must be set to false and in the „comma separated own pair list“ only the symbol (e.g. XAUUSD) that is used in the tester has to be input.
→ for live testing (better on a demo first..) please do NOT use small timeframes and many pairs with only one entry condition. The EA will open, close, modify in such a high frequency, that your broker will close your account faster than you can click. Happened to me ;-)

Have fun!

REMEMBER

This is a code for learning and testing purposes only. Everything you do, you do on you own risk!

In no event I will be liable for any damages whatsoever.

Thanks a lot for starting this journey with new thread
I have very little knowledge on coding part but from time to time I can test with the setup I am having and present the case here .
Thanks .. yes thanks to Richard also he has given lots of new ideas to use the old blessing code definitely in new way.
Remember that post?

Well, I used the settings and made a backtest from 01.Nov.2019 to 10.Jan.2020. 5 Minutes timeframe, for all 28 pairs. What can I say: that already looks like the winner to be tested on the Blessing-Multipair. Can't wait for Sidney open...

Thanks for new 3dand new blessing multipairs...
So if i understood the result above are backtested using the 5min set file from other 3d right?
What about set file you posted xususd... ?
And how many max pairs do you seggests to use to avoid broker limits?
Thanks

Your welcome! And thank you for joining the thread!

Right! I have a bunch of setfiles from the other Blessing thread. I picked that one for backtesting first, as it is alread used successfully on a live account (with the original blessing).

Quoting cescof

That is just a set-file example for backtesting with the MT4 strategy tester. One pair, no 28 default pairs.

Quoting cescof

The number of pairs is not the biggest problem: the entry conditions are much more important. The default setting has only the MA as entry indicator. This opens trades for almost every pair instantly. Good for testing, bad for trading ;-)

The set-file I used for backtesting is using Bollinger Bands. Does not open too many trades over the time, not even in the M5 time frame. You can see it in the statistics. Okay, that's backtesting on a demo account. Tonight I will start with forward testing on the demo account...

I should get some sleep as well...

Do we have a setfile to test on monday?

Basically you can use any testfile from older "original" blessing versions. Parameters that do not exist anymore will be omitted, new parameters that are not contained in older setfiles will use default settings.

As the default for BlessingLite Multipair is UseDefaultPairs = true, you just need to load any blessing setfile that you like and then get started...

I will try that one tonight:

Good show!

You might want to create a settable minimum delay between trades to fix the over-trading problem. That's a common feature on multi-pair EAs.

You could save the time from the most recent open of each pair, then compare with current time each attempt to open another trade. Only allow new opens to succeed if elapsed time is greater than some externally set value.

Good luck!

Thanks for the feedback Richard! That's the way I hope this thread will continue...

The challenge is not only over-trading, it is also the "over-modifying". Moving TP, moving buy/sell/limits/stops: all this has to be monitored. I will wait and see how the EA will behave tonight, with the bollinger band indicator compared to the MA. In the backtest even on the M5 timeframe bollinger is much more calm...

Good luck!
Thanks... but luck is not the only thing I need: my idea was to use this thread as an open source community. Everybody can and should take a look at the source code and see where it can be improved or find these small bugs... if someone knows how to transfer the code into mq5 quickly, this would be advantageous for debugging. Setting breakpoints in the strategy tester would already save hours during development.

Okay, next to-do would be the delay parameter and something like this (setting from a dashboard EA):

Thanks for your effort! Looks interesting.
The EA works fine in the Strategy Tester but when I try to install it on a live chart, my MT4 won't let me. Accordingly, the following error message appears in the Journal:

"2020.01.12 10:29:02.624 'BlessingLite_3_v3.9.6.24_beta' is not expert and cannot be executed"

Which build are you using? Did you put the EA in the right folder?

I used the mq4 file in different broker installations, all build 1220. No problems. Compiles without error.

I initially encountered the same issue with other Blessing versions and solved changing int start() method with void OnTick().
See here:

Perhaps it could be useful to update source code naming according to new MT4 Build 600+ compliance.
Best regards.

Jipp, I was reading about that as well. Anyone knows why it works fine on all my new 1220 build installations?

Remember: when you change to OnTick(), you have to change also all the return calls!

Just to verify, I placed the EA on to a live chart with no issues, not tried ST but the assumption would be, no issues, (MT4 version 4 build 1220) still testing the older version of blessing.
Ursinho, well done and good luck on the new threadD
I don't need to be good at the game, only good enough to beat my opponent,
Just to confirm; I am using build 1220 and the EA is in the correct folder. I had been using Blessing_3_v3.9.6.13_beta without any issues.

Any messages when you compile it in the Meta-Editor? I will change the code to OnTick when my daughter goes to sleep (probably not before midnight ;-)) )

Yes, I forgot to write that to maintain backward compatibility with Blessing code I renamed int start() to int DoStart() called by void OnTick():

void OnTick()
{
int retValue = DoStart();
}

int DoStart() // ex start()
{
