Hello,
Where to get a list of all (absolutely all) upper case Standard constants ?

A lot are missing here: http://docs.mql4.com/constants
Exemple:
VAL_OPENPRICE
VAL_TICKET
VAL_STOPLOSS
TIME_DATE
TIME_MINUTES
SELECT_BY_POS
OP_BUY
OP_SELL
FILE_BIN
FILE_CSV
FILE_READ
FILE_WRITE

Thanks.

In the editor, click the Dictionary tab and then select Standard Constants. Should be fairly complete. You can probably copy and paste them into a Word document or something.
