Hi All,
Here is the proteus answer on forexpeacearmy forum:
I think mr. arryex did not understand the purpose or how the indicator works.
Mr. arryex, this is not an attempt to deceive you or our users by any means.
It is clear from the website description, from the screenshots and from the video, that this is how the indicator works. Even if by some chance it was still not clear for someone, they were and are welcomed to send an email to
[email protected] to clarify any questions or doubts that they may have, before making a purchase. This is repeatedly written throughout the website.
You complain of that "the indicator is not as what they claim, i.e. neural network prediction for MACD(20,200,20)". But it is exactly that. The future values are predicted using a neural network algorithm, embedded in the dll file.
You also complain that previous prediction lines will be overwritten with the real value of MACD. This is true and I never claimed otherwise, but if you think about it, seeing as the prediction is made for 5 bars in advance, there is no other way to display the information except to overwrite previous values. I'm going to try to explain why: at each bar, there can be one value. Consider the 5th bar (let's call it 'X') in the future gets it's prediction as value v1. When time passes and the current bar finishes forming, the prediction is refined and bar X in now the 4th in the future and gets a new, more accurate value v2. This happens repeatedly until bar X becomes the current bar forming. So bar X gets 5 values as time passes. Which one to display and why ? Who makes this decision? If I choose the first value, someone else will complain that it should have been the 2nd value, and reverse. There might be some value in leaving the last prediction drawn instead of replacing it with the real MACD; or maybe adding more indicator lines; this is something that the few developers that I have will look into, if many people request it.

Here is my answer:
Hi mr. proteus,
In my opinion:
- It is not fair to claim prediction accuracy more than 90% for predicted values 1 bar, 2 bar in future, In the meantime you remove the predicted value and overwrite with the real values.
- I understand most of predicted indicators are to predict the value in future, but to see the perfomance need to compare the past predicted values and the real values. I am sursprised that you remove the predicted indicator then overwrite with the actual value. Means forget what has been predicted, what ever your trade position and just see the next predicted value.. As the real sample, if the predicted MACD tell that next 5 bar in future will be cross down, after 3 bars completed your predicted values said cross up...meanwhile the previous prediction has been gone (overwritten with the real values).
- I could not confirm on real that your indicator has more 90% accuracy as you claimed. The statement about indicator accuracy make all people interested to buy..but in fact I do not get it...
- You said there is no other way to display the information except to overwrite previous values. You can... put predicted and real values in different buffer and display both of them..so you can see their past values..Only by comparing them you can claim 90% accuracy. You need to learn more how to to make a good indicator prior selling it, try for your self..
- I am curious when we ask you the real perforrmance of your indicator or even by creating an Expert advisor, i am sure you don't have it..
My conclusion:
- your indicator only display next predicted values but forgeting what has been predicted (either good/bad prediction) after new bar coming.
- Your accuracy can not be confirmed in actual because you overwrite the predicted with the actual values.
- Claim 90% accuracy is not correct for me...
- Your indicator is repainted, since you remove/change/overwrite the predicted values.
