    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…

    Thanks a lot Lucas! I’m adding this indicator into the Library. Don’t hesitate to add more! 😉

    Variables have been added directly to the code… You can add the variables in the input table of probuilder if you want to.

    Sorry, don”t know how it was working without…
    Nevermind, you can add line 14 : long = 25

    Thanks a lot; what prompt did you use?

    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…

    For example, for the conversion of this code which is rather simple, i had to help him a lot, as it was lost with nz() and na() instructions and how to translate them (even with using if then else). It tooks more than 3 hours while i would have need only 1h to do it without chatgpt…

    I made the conversion yesteerday of 3 or 4 indicators, so i had no time to test them yet.
    But, i think yellow candle does not appears very often also in the original post on tradingview :
    https://www.tradingview.com/script/791WkWcm-blackcat-L3-Banker-Fund-Flow-Trend-Oscillator/

    As you can see, even while scrolling left and right the chart, yellow candle appears only once.

    It is because of line 62 :
    bankerentry = (fundtrend crosses over bullbearline) AND bullbearline < 25 You need to have a cross over while bullbearline is below 25. What you can do is to add a variable call it SupertitiThrshold = 25 (by default) Change line 62 : bankerentry = (fundtrend crosses over bullbearline) AND bullbearline < SupertitiThrshold Then play in configuration table with that SupertitiThrshold until you see as much yellow candle as you would like

    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.”

    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/len

    IMO, it should be coded as below:
    ma = undefined
    if srcValue1[lenValue1] >0 then
    ma = sumf/len
    endif

    You are right Nicolas, with my convrsion ma would be equal to 0 or equal to sumf/len, in yours ma would be undfined or equal to sumf/len

    09/18/2023 at 9:19 AM #221190
    Nicolas

    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.
