Hello,
EasyLanguage performs IMPLICT loop (hidden from the user thus non-controllable, iterating
the formula as many times as there are bars).
This implict loop among other things makes EasyLanguage way slower than AFL, but allows EntryPrice
constant.
AFL is different because it has NO implict loop that you can not control in any way.
Instead it allows YOU to choose if you want loop for given task or
if you can achieve what you need with ARRAY PROCESSING:

Some applications need looping some not. If you need "EntryPrice" you may either
use loop as in the example I provided or use ApplyStop which handles lots of exit scenarios
based on entry price.
Best regards,
Tomasz Janeczko
