keep in mind that you should always use SL, its part of the Forex gospel. If you don’t, you risk an unknown % of your account. You could do 3:1 leverage, go to sleep and find out in the morning that some news came out or something and the market moved against you 100-200 pips! Suddenly you are out 3-6% of your account! Draw down can be a *****.
Of course what you say is also very exciting and an excellent system.
It may offer less trades, but I’d bet that you can get 75% winning trades this way.
Here is a helpfull suggestion.
Instead of not useing TP, try a manual trailing stop.
set SL at some level, such as 50 pips, which is 2:1 leverage at 1% account risk, or 4:1 leverage for 2% account risk.
Then check in occasionally, as often as you can, and if you see 20-29 pip profit, change SL to +5, 30-39 pip profit, +10, over 40 +50% profit.
The reason this is a good idea for your system is that an RSI over 80, or under 20 is great for swing entries, but what about exits?
You have no confirmation in your system. No way of saying, “Ok now its time to end it, and celebrate.” Without TP you could go to bed with a 200 pip paper profit and wake up to find out your up only 35 pips.
With a manual trailing stop loss you at least lock in profitable trades and keep them from becoming negative.
I will test your system on a 3 hr chart. Good thinking overall.
