Spent few hours with chatgpt helping me (or maybe i was helping him?:-)) to translate an indicator from tradingview.
Finally we did it, but it tooks twice or 3 times more times than if i did it alone…

Whatever the prompt i use at the begining Chatgpt does a lot of errors, syntax errors and confusion between the different languages (for example, it sometimes creats new instruction when it does not know how to translate to probuilder…)
What i don’t like is that sometimes it seems to forget all i’ve said before and does simple syntax errors it did not before… Weird! AI they said? Then Ai is dumb from time to time…
For functions, the prompt that seems to work is to tell him : whenever you meet a function, do not translate it because probuilder dos not support functions yet, but instead apply the logic of the function each time the pine script will call the function later in the code.
Also, chatgpt (v4) is not comfortable with probuilder when it comes to ploting… So it often needs some hints to know which instructions to use for plotting (Drawsegment, drawcandle, drawpoint, drawtext or simply return…)
When it comes to color, i tell him to split colors in 3 differents variables with r g and b values.
I tried to feed him with a list of all instructions that exist in probuilder, but his level in prorealtime coding remain the same from my point of view…

Sometimes ChatGPT is funny… Or maybe upset as i made him work to much ? See below his last answer :
“If you’re serious about porting this over to ProBuilder, you might consider working with a developer familiar with both Pine Script and ProBuilder to ensure accurate and functional translation.”2 users thanked author for this post.
Just a tip, this kind of “direct” translation from Pinescript is not accurate :
ma1 = not (srcValue1[lenValue1] = undefined) * (sumf1 / lenValue1)
(in this case you are multiplying the result of the boolean with (sumf1 / lenValue1) )The original code was using a single conditional statement within a single line, and with (na) testing:
ma := na(src[len]) ? na : sumf/lenIMO, it should be coded as below:
ma = undefined
if srcValue1[lenValue1] >0 then
ma = sumf/len
endif1 user thanked author for this post.
To be clear, think of this:
ma := na(src[len]) ? na : sumf/len
as this:
if IsNaN(src[len]) then ma = NaN else ma = sumf / len
in ProBuilder, there is no “NaN” state (Not a Number) by default, until you declare a variable as UNDEFINED. So it is better to test if it’s equal to 0, because all variables equal to 0 at start of code.
Sometimes it is useful to set a variable to UNDEFINED, to make it not visible on chart until its first calculation for instance, but keep in mind, that UNDEFINED can only be assign once.
