Hi,

https://financial-hacker.com/algorithmic-options-trading-part-3/

The scripts from the above example fails. For some reason
Code
StartDate = 20110101;
EndDate = 20161231;

is getting misinterpreted as 2019 to 2017.

Code
Zorro 2.25.7
(c) oP group Germany 2020


aaa_strangle_without_roll compiling....................
Error 016: Date range 2019-12-31 14:30:00 - 2017-01-01 23:58:33
Error 055: No bars generated


I downloaded the SPY.t8 and SPYa.t8, but I suspect it is not finding it.

What's the next step here?
