Z13 with Interactive Brokers

Hello,

i am trying to get the Z13 strategy to work with Interactive Brokers. I have set up everything according to the manual. The backtests are working fine.
When I try to run the strategy I always get the message: Not enough capital!
I have tried it with a real and a demo account with different slider settings, but always get the same message. At least the demo account must be sufficiently
funded with 83000 USD and a slider setting of 5000.

Any ideas?

Thanks a lot....

I think not that this is enough for options trading, you need more than 5000 margin for a SPY option.
