If Robinhood can give spread & commission free trading why cant any Forex brokers do the same?

Ive found a pretty good system scalping but a huge chunk of it is taken in commission, which means one "break even" day can set me back a couple days worth of profit.

Anyone know know of a broker that maybe has a monthly subscription with free trading?

Also can a FX broker with ZERO FEE trading TECHNICALLY be done?

This question also came to my mind. Yes, fx brokers have several ways to make money off of traders, technically commissions are not necessary (and I do not mean mark-up on spread as "commission-free"). Most of them cheat anyway. Any broker that does not have spreads of 0.1-0.2 pips at all times during main sessions (EU/USA), is interfering with price (imo) and (so) can buy cheaper or sell more expensive to trader and make money from the spread elsewhere..
