ZRXBTC 4H: High profit - low Drawdown by Riding Trends

ZRXBTC seems to be perfect for technical Analysis! It's so easy to identify strong Trends.
I found a highly profitable Setup on the 4H Timeframe. You'll get only a few Signals per Month, but according to the Backtests, more than 90% of the Trades are profitable.
Sounds almost too good to be true? But it's getting better: Depending on your Account-size and the Position-sizes you are using, you'll achieve almost 80% Net Profit with less than 5% Drawdown!
Here is a screenshot with the Backtesting Results from TradingView's Strategy-Tester, and here are the Settings that were used.
