My EA Strategy for 3 minute BO

I made an EA for my long term project on Binary Option trading.
TimeFram = 1 minute
Signals are:
Green Spike = Buy (for 3 minutes expiration)
Red Spike = Sell (for 3 minutes expiration)

Strategy:
VMWA (50&200) = Trend Indicators
RSI (30) = pull back entry signal on a strong trend
BackTest = 80% Winning Rate

Improvements Needed:
>> Better Entry Star Signals
>> How to be automatically connected to a certain broker for HFT
