Best prop firm for automation and eventual "A-book" trading

[caementarius]

Hello Trading Friends!

Of the many evaluation firms, are there any you'd suggest I look at particularly for automated trading approaches? Here are some considerations I have:
- I need to use exogenous order signals generated from data science models (Python or R) - I think I can do this using NinjaTrader or MT4/5
- I have data feeds and historical data from IB
- In retrospective backtest, I have hold-times that average around 20 minutes and use signals from minute data in the modeling - it's not very high frequency
- I would like a situation where an eval would lead to "A-book" trading where trades reach the market and trader interests are aligned
- I would like to trade major indices and commodities/futures, with crypto/forex and SSF being a bonus

TradeDay may meet these requirements, but I'd be interested in other suggestions.

Have a look at APEX. But I would rather trade CFDs and go with FTMO, which is best prop firm around. Actually have a 10% discount offer.

Thanks for your reply.
Apex does not allow bots and based on what I have read, FTMO is all sim trading. I won't make a value judgment on that, but I want actual alignment with the firm and to avoid a setup where my success costs them money.
