I need some help getting started:

1. I have a Zorro S.
2. I have an IB account.
3. I want to trade stocks and ETFs using the Z9 strategy.
4. This strategy requires first training on historical data
5. Documentation says use Stooq for historical stock quotes
6. Stooq now requires an API key that I cannot get thru the methods suggested by JCL in this forum

My two questions are:

1. If I cannot use Stooq, what historical data provider can I use?
2. What changes do I need to make to Zorro.ini, the strategy, or assets CSV file to use a historical data provider other than Stooq?

Thank you

Addendum:

Is anyone else using Zorro S to trade with the Z9 strategy? If so, what historical data provider are you using? How are you alerting Zorro to this new provider?

Thank you!
