    Am I going gaga or what!?:)

    Attached is what I see using the code below from the standard PRT Indicator set.

    The GRAPH function is showing when the MACD Signal Line crosses over zero NOT when the MACD crosses the MACD Signal Line!?

    I’m sure I’ve highlighted this before, so maybe  my brain is doing a double take on (my) incorrect logic or way of looking at things?

    Surely such a basic Indicator as the MACD can’t be wrong in the standard PRT listings???

    Thanks

    PS Attached is the choice I have in the PRT Listing and what I picked for the GRAPH function.

    I also got a little bit confused one time and I think the names of the lines are little strange. Look here for the legend. 😉

    But that is pathetic and totally confusing of PRT???

    What chance have newbie coders got if they have to remember a work around code for the MACD????????

    MACD Line is universally accepted as the faster line / blue line and the MACD Signal is universally accepted as the slower line / red line  … not the flippin ZERO Line!!!!!!!!!

    Blue line (named MACD) and red line (named Signal) are shown as such in PRT screens and appear as such if one selects Indicator MACD.

    Honestly at times I feel like packing it all in!!!!!!!

    Come on PRT Moderator please comment???

    PS I’m done for the day now … I feel like punching somebody’s lights out 🙂 … the more so as I’m 99% sure I highlighted this ages ago via the PRT Suggestions Form … but of course I can’t check because there is no facility  for looking at previous Suggestions etc on the PRT website!

    Only way I could is to do search on my emails and then only if PRT replied (which they haven’t on my last 2 Suggestions I sent in!!!) . If I search for MACD  on email imagine how many hits I’d get.

    If PRT just sent an Automatic reply with a copy of what I sent them on the Suggestion Form then at least I’d know what I’d sent in to PRT.   I’ve been over all this also time and time again!!!! Time to give up and start living again!!!!!!

    As you can see this has really rattled my cage!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    When I discovered that I thought this must be an error in there their programming. Can’t imagine that this was done by purpose. However with the definitions I wrote above it works – as confusing as it is.

    Yeah but a Newbie Coder would just read up on websites what MACD is then think … ah this sounds a useful Indicator that loads of folk use!!!

    Then Newbs Coder starts coding and selects MACD crossing over MACD Signal from the standard PRT Indicator listing …. and yes they are called MACD and MACD Signal … then the Newbs coder finds the results not as he expected (and as all the dozens of websites have educated him to expect!).

    Come on PRT get this sorted  ASAP for the sake of our Sanity and belief in your Product!!!!????????

    Align your terminolgy / calculations for the MACD with everyone else PLEASE

    It also confused myself each time, you are not alone grahal 😆

    I’m now used to construct my own MACD in my own code or for customers. It saves me from long debugging sessions like I had in the past because of the names of these instructions. If I remember correctly we already had this kind of discussion also for Alligator and the colors differences with other trading platforms.

    The point is that the command

    does not yield the MACD signal line, but the so-called MACD signal (in the standard PRT indicator), which is the difference between MACD and the signal line. Someone has mixed up these two while coding them.

    But who uses MACD or similar indicators anyway for real trading systems ? In my eyes, they create too many unreliable signals because they can wiggle around far too often and quite heavily. Maybe this is a reason why nobody has reported this bug so far.

    Quite! MACD is sold as one of the most important indicators and yet I don’t have a single strategy that uses it. Glad to hear that I am not the only one.

    I actually use MACD in strategies that I run live. Both as entry signal or filter. Works.

    I’ll add it to my list to revisit then. Short time frame or long time frame strategies Despair?

    Always look at whom you’re talking to…

    I uses it for entries on daily timeframe for longer term trend following trades. Then I use it in breakout system that can be as short as 15min TF as filter. So I take only long trades if the MACD>0 or something like that.

    I agree. I use TRIX as a similar filter in backtests, and a strategy only goes long (in backtests), when TRIX > TRIX[1].

    The real point is that trading has no exact rationality as people try to pretend it here.

    Trading is chance. And working with it.

    Trading is trying to quantify chance to the point where you are willing to put money on it.
