@zereleth you have to set your desired input ranges in the Expert properties.
For example, moving average could have start=3 step=5 stop=100,
and then mt4 will calculate results on ma periods 3, 8, 13, 18, ... 98, 100.
What do you exactly mean by 'more than once'? Do you mean on the same bar? Then a 'No trade' block (for buys) and another (for sells) should be put on top of your launching structures.
