As usual, it is obvious that the summer vacations are here.
When it comes to coding, technical analysis or trading using words like "afraid from fisher" is something that that is highly unusual and I must say odd. Afraid of what? This is not a game. It is supposed to be a business of making money, not "jumping in, and surviving" for the ones that "dare". I rather think that there are people that need to make money so bad, that they choose to "believe" instead to know (or, at least, to learn)
No wonder that that 95% still exist

Of repainting only 2 bars : you do not need opened market to test that

Here is a test picture of Fisher yurik indicators posted on post #1 and #4 of this thread (and reattached here - just in case) that will help count the bars that are repainted.
An interesting reincarnation I must say. The one I know at least cleaned up the "double" bars.
The additional error it is caused by the line that "makes sure that only 2 bars are repainted" (line 68 of the source
for(i=limit-2; i>=0; i--)).
Sorry to disappoint everybody, but that line does nothing of a sort
