I am planning on backtesting a system similar to the Cowabunga system tomorrow, but using longer time frames, (determine trend with weekly, trade daily, and time entrance and exit with 3 hr).
I plan to determine the trend using the EMA crossover method and I was hoping to get some advice here on which EMAs would work best for trading daily charts?
I know Cowabunga uses 5 and 10, but some brief experimentation with 10 and 20 on EUR/USD and USD/CHF (only for the most recent 7 months) indicates that perhaps this combo would be better in that there are less false trend changes, (the kind that force you out of a profitable trend trade).
For example, using 10 and 20 EMAs, the EUR/USD rally began in Mid March and has not had any cross overs since, (only close calls and perhaps a touch, but no confirmed cross over). This would have resulted in 1500+ pip profit and counting. The 5 and 10 EMA did have crosses that would have caused one to exit profitable long positions several times as well as some false long signals, (I will only trade the weekly trend, so no shorting the EUR/USD for now).
A brief check of USD/CHF shows the same thing, 10 and 20 would have kept you in a short trade since late April, for a 1000+ pip profit.
For my system to work, it is rather important that one not prematurely exit such multi-month, 1000+ pip trades, since the SLs you need to use are enormous, (200-250) and limit you to 1.5:1 leverage at best, (assuming you risk 2% of capital/trade, if you risk 3% then leverage can be increased to maybe 2-2.5:1)
Any suggestions? Perhaps other combos I have not considered?
