Best broker for Dax scalping

Hello, I have been introduced to a Dax trading EA that my old broker simply couldn’t handle.

After reading some interesting posts on this forum, I have narrowed down my broker search to Yadix and fx open.

Yadix has a good reputation for Scalping and EA trading and the conditions are good, no restrictions on open, close, pending and limit orders, so I have opened a $500 account there and going well so far.

Fxopen have cheap options for trading but are they suited for aggressive and profitable systems?

Any opinions please especially for Scalping indices and fx?
