This is the arrow added by mrtools teacher for RSI_filter (70-30) .mq5.
(There is only one arrow for each up; there is only one arrow for each down)
It works very well!
Looking forward to seeing you upgrade it to add MTFs and alerts! Infinite merit!
Better to put the level option in the settings menu!
extern double flLevelUp = 70;
extern double flLevelDown = 30;
