I have prepared the following setup for Z13:
- Downloaded SPY EOD data from Stooq and converted into SPY.t6 file
- Downloaded all actual SPY-options data from Yahoo JSON and converted into SPYa.t8 file
- Set the Preload flag in Z13.ini to 1

I assumed, the Z13 script would use the SPY.t6 to calculate the volatility filter and use the SPYa.t8 to select the option combo to sell. I wanted to sell the resulting combo manually.

But when I click „trade“ with IB plugin, the script doesn’t not run - the error 053. (attachement)

Will someone advise ? Am I right - I do not need any IB data subscription to trade Z13 manually ? Just Eod SPY data from Stooq and one day SPY-option data from Yahoo ?
