minor comment:

In the article on the website where it says "Only the calculation of values for the TSIBuffer[] array needs to be optimised, but this is not difficult to do in the same way as was used for MTMBuffer[].
" "

Here comes the code :

//--- now let's calculate the indicator values
   if(prev_calculated==0) start=r+s-1; // set the initial index for input arrays
   for(int i=start;i<rates_total;i++)
     {
      TSIBuffer[i]=100*EMA2_MTMBuffer[i]/EMA2_AbsMTMBuffer[i];
     }
//--- return value of prev_calculated for next call
   return(rates_total);

where you need to add the value of the start variable if prev_calculated is not equal to 0. This missing point is present in the source.

nothing is missing. the code for start is above.

you should look at the code I've given and compare it with the source.

you need to add :

else start=prev_calculated-1;

you need to add :

else start=prev_calculated-1;

why do it repeatedly?

this repeated line is in the source, but it is not critical to the algorithm.

sergeev:

and why do it again?

there is this repeated line in the source, but it is not critical to the algorithm.

Yes, indeed.

I can't find this article through Articles - Indicators. It has also disappeared through Examples - Indicators. It was just a few days ago.

From bookmarks it opens normally.

Everything seems to be normal, in place:

It was like this. After looking, there was an update, it's now 4 pages there, and the article is back up.
