Thks understood … but sily to me. A strategy is not just a signal … but a comprehensive set of rules which drives to profit.

If one starts to change position sizing, risk management, SL management… then the returns maybe be significantly lower.

And they won’t blame themself to have changed the default setup.

And even if I wanted to give users a set ot customizable value based rules, this should be able via input variables automaticaly set up when importing the ITF files.

I still don’t understand the PRT approach to be a nice looking interface but still a low end featured tool when it comes to programming trade engines.

This being said … ( I had to write it) I appreciate your help and your prompt answer.

B.

Thks.. but as usual with PRT … it doesn’t work. One limitation leads to another … and more you look for a workaround more you face news issues.

Of course I tried to split as much as possible but …

Nicolas’s answer (‘ soit reprendre l’intégralité du code de l’indicateur dans la  stratégie.’) takes us back to the original issue.

The main point here is who are the PRT system architects … and do they really understand what trading systems are.

@ Nicolas,

Have theses tehcnical issues not been discussed as part of market place ?  Any MTF system seller won’t be able to protect his/her code.

IG has MT4. I’ll switch to it for this algo.

Hello Nicolas,

I can fell your committment and involvment in PRT. Also, I can see it too through the Prorealcode web site.
No doubt you deserve many thanks and outstanding success in your journey. And my comment does not remove anything to it.

Still, and by far, PRT is not the best platefrom to trade. And again, this does not make it the worst.
Most people appreciate the look and fell, the easyness of writing colorfull indicators … and so on.
It is definitely the best platform for trading as a leisure.
I, even, have good reasons to use it … since I do.

But still, being able to see and accept its weaknesses is the best path to innovation and success (especially for a vendor)

I am fully open to a live conversation with you on PRT and other plateforms… but … I wish we share facts rather than concpets or comparison.

“Many many many sellers ” …. sure… but what others do is not always right… and trading is not the only domain where it happens.

“I suppose you are not using it correctly. ” …. sure too… but the ‘timeframe’ feature not being able through the CALL function has nothing to do with my skills.
The fact that PRT itself recommend not to use too often the CALL function … has also nothing to do with my skills.
Btw, I split my strategy to run using external indicators and CALL function. Back testing on one year of data (intraday) rose from 10 seconds to 9 minutes … has also nothing to do with my skills.

“One of the reason is that PRT doesn’t allow black box systems to run on their servers.”
“It is also useful in 2 ways: on the customers side, it protects them from being scammed with fake programs … ”

I disagree with you. People coming to trading should protect themself from wired dream sellers.
I don’t think that the role of a trading platform is to protect people from greed.

And I would appreciate you tell me more about what a ‘fake’ program is
Whatever, the platerform, as long as the program must go through a compilation process,
and allows a full back test of the delivered strategy before being ran live… there is no fake.

“and on the vendors side, you are giving the possibility for your clients to act with plain knowledge of what is the code about ”
Again, I disagree with you. And I am suprised to read that you think that having access to code gives plain knowledge.
First because, even as a devlopper, I ran into situations where I gave up trying to understand other’s people code.
Reading a book doesn’t mean you understandand/or learn anything.
Second because, yourself, here, https://www.prorealcode.com/topic/prt-bands-trend-following-prorealtime/ , you wrote “There are indeed certain technical indicators subject to intellectual property (as is the case of RocNRoll for example), PRT Bands is an indicator exclusive to the ProRealTime platform. We are not going to go into the topic of the indicator code visible or not, it is unnecessary, I think it is best to use it as designed.
”
Should the code be hidden depending on who is making money with it ?
Should only great ideas from others be freeware ?
