I need MQL to MQL4 code transformation
convert mql to mq4
I will try to knock it out for you this weekend.
What does it do?
RSI versus other signals
I will give it a run after prime time today; the two are not that different.
I just have a SDJ (stupid day job) right now.
I do almost all MQ4 now, it is really a huge improvement (IMHO) in capability.
I walked away from a great alligator system just because my broker forced me to change.
The biggest question about your really sweet chart is the same question for a lot of great looking charts, do they perfrom in real time as signals occur or they always map in past hindsight perfectly and then get all squirrelly in the tick by tick of the present? I can give lots of indys that map out great looking charts (try the LSMA for example)
Maybe you got something here, it never hurts to run it up the flag and see how she flys, its why they made virtual accounts...
Real time
It doesn't "re-paint" the past. That is a real nasty thing made by useless indicators. I remeber the first time I've encountered an indicator that re-painted the past... I got so excited looking at the past signals and then - a massive dissapointment when I saw that in realtime it's useless.
This one works in real time! I'm sure about that.
I can't wait to put it at work. Don't forget to post it here 
.
Have a nice weekend.
Have you finished this indicator?
Hi Roguewave
Have you finished this indicator? Please post it here.
Thanks.
Here is my conversion. I am not sure it is correct as I could not compile the code you posted above in the MT3 editor.
It looks good to me!
Thanks treberk!
I don't think it's incorrect. It looks good to me!
Good luck and good trades!
Hello cucurucu,
In the script (mql for mt3, post 1 ), there are errors :
28;9;1;42;unknown token - token "\"
28;9;1;18;variable init expression error - token "\"
.
Hi BrunoFX
I have never used this indicator for MT3 (that particular code I've posted) so it might contain errors. That code is copied from a website.
However, I have seen the Inverse Fisher Transform of RSI on some charts before(different platforms) and I'm glad that this one posted by treberk looks as it should. It has only one minor flaw: the +/- 0.5 levels (HiTrigger & LoTrigger) are not drawn. Instead, is drawn a 0 line. This one can be fixed by adding those levels from the indicator properties window.
Thank you anyway for your info.
Please take a look at the article attached.
Hello,
Thank you for this answer and this document. Do you use this indicator? if so, which osnt your rules of exits?

Hello,
Can somebody "translate" this code from MQL to MQL4 ?
This is the MT3 indicator and I would like to use it on MT4.
Please post the indicator here(the code or the mq4 file).
Thank you.
