Thank you Pierre. Let me be clearer about exactly what I'm asking.
The problem is not with the values in MyArray. The values that are returned
to the calling indicator match those values in the function perfectly. So in
fact, the 2-D array was passed correctly to and from the function.
The problem is in the serial values of MyClose before the If...Then
statement vs. after the If...Then statement.
You would think that it should not change, but it does. There is something
going on with TS internal logic that when you hit the "pause" button in
code, then release it after LastBarOnChart, any serial variable "filled" on
the first run through, no longer holds it's historical values.
Perhaps I should just turn MyClose into another array and be done with it.
Regards,
Gene
