Help me program interpolation and extrapolation. Tried to figure out complicated examples (like extrapolator indicator), but couldn't. I tried to find something similar, but there is no interpolation anywhere, only averaging. The picture shows an example of such interpolation and extrapolation based on the Fourier transform. How can I get a function BETWEEN BARs to be plotted not as a straight line but, for example, as a cubic polynomial or in some other way (not fundamental)? At least simple examples, the extract itself or links, not necessarily with mathematics. Thank you!

Hello.

What may be the problem, the Expert Advisor passes the test in the tester on the demo, but in the tester on the real account it fails. I have the same conditions.

 
Put the EA on tf=m1 and see what the log says when the EA signals to enter.

Doesn't open anything at all, immediately after starting the test it says the following (in the picture)

I.e. it appears that it loads the zone and immediately deletes it. There is no such thing on the demo. Please advise what is the problem?

When compiling, it gives out a bunch of errors. Help me figure it out, I can't see where I went wrong myself.

TRY THIS FUNCTION AS A SAMPLE.
