Function call bug

2019年9月23日

This is a code to showcase a function call bug in PineScript.

Problem description:

• When a function is called from inside of if-then scope, this function may return an invalid result.
  

Code description:

• Two identical code pieces are used to perform simple calculation. The only difference is that one piece has a part of its code wrapped into a function.
  

Expected result:

• All green and red crosses should appear on the same candles. These crosses are calculated by identical code.
  

Actual result:

• Some red crosses appear on the candles they should not appear on.
