Yes, that is the idea, but although the code seems right, it does not execute right

Great , might i ask about the 1008 to 63 ? why this pair ?

Great = We are indeed checking the upper line only , add another clause in the if statement for the lower line.

Also , when it does not find a match , it should use the previous DevStep correct ?

These are just the MA settings I use.

Adding the lower line now will not change the functioning of the calculation. First I need the code to be working correctly and than I can add the lower line condition.

Adding the Lower Line will change the "idea" of how it operates , regardless of whether or not the code is correct .
The idea with the lower line is closer to what you are trying to accomplish so i would do that first .

Hi Lorentzos,


Thanks for the work your putting into my request.

The code you send can draws two lines of period 63, but not the lines of the 1008 period, and its the last one that is required. As the code is now, it will never work though because the logic in  Line 102 excludes every possibility.

The upper envelope and the lower envelope of a slow period (1008) can never be between the fast period envelopes at the same time.


It is like I explained before, just one of the two slow envelopes either the upper or the lower will be between the fast envelopes at any given time. That is why I road that once the code for the upper slow envelope is working, the code for the lower slow envelope is easily added.

Hi Lorentzos,


I made some changes to your code, and guess what,..... it is working.

Thanks a lot for the help you gave me.


I wish you a very nice evening and prosperous trading.
