ADX Breakout strategy for insane returns on the EUR/USD 30min

Tuning Rob Bookers ADX Breakout Strategy on the 30 min EUR/USD looks to be a very constant high return if you can handle the drawdown. I will begin trading the strategy with a small cash account to see how it does live.
I am also using the same strategy on GBP/JPY except i seem to be able to control my losses more with a trailing stop as this pair likes to get near the limit order and then turn on occasion.
