Please i need to help
Please . can you add another moving average . Median .
Fore example : FastPeriod=10
MedianPeriod=50
SlowPeriod=100
Open order when moving average 10 cross moving average 100 .
Close last order when moving average 10 cross moving average 50 .
Loop
More explain :
When Fast MA crossed above slow MA so GO LONG . and when Fast MA crossed below slow MA so Exit Last Order And GO SHORT .
I Need to update it to :
add third MA . Median MA .
- When Fast MA crossed above slow MA so GO LONG . and when Fast MA crossed below Median MA so Exit Last Order . and when Fast MA crossed below slow MA so GO SHORT .
- when Fast MA crossed below slow MA so GO SHORT . and when Fast MA crossed above Median MA so Exit Last Order . When Fast MA crossed above slow MA so GO LONG .
thank you
