Hello,
For example, take a look at this simple code:
Buy = Cross( MA(C, 5 ), MA( C, 15 ) );
Sell = Cross( MA( C, 15 ), MA( C, 5 ) );
There are 2 repetitions of same function call with invariant parameters:
MA(C, 5 ) - is called twice
MA( C, 15 ) - is called twice
This can be written in more efficient manner using variables:
shortma = MA(C, 5 );
longma = MA( C, 15 );
Buy = Cross( shortma, longma );
Sell = Cross( longma, shortma );
That is what I meant.
Best regards,
Tomasz Janeczko
