Thank you for answering mate. My problem with JMA is different, I have the code of JMA in folder "experts",then "indicators", but when I get in the terminal / after restart/ there is nothing. JMA is the indicators list but I can not attach it to the chart. When I have chart with two or more indicators, and press with right button over the indicator I have on the chart , then press "indicator list" I have JMA there, but I can not see it on the chart. Anyway I fixed that problem.
Thank you again for the info and the links about NN and MM. I will check them all.
