I trade only the Weekly, Daily and H4 charts focusing on very high-probability setups depending on price patterns (pinbar and engulfing bar) found around significant S/R levels. It's a swing trading discretionary system. I don't take a lot of trades but it's always high-probability setup in order to earn money consistently.

I trade this system successfully since 3 years now. I'm a naked trader (I trade without indicators). I use the only reliable information on Forex : the Price Action.
I risk 2% per trade in order to avoid strong drawdowns. I never change the risk exposed on the market. The average R:R aimed is 1:1.
Of course, I use stoplosses. The lot size is always calculated relating to the stoploss position to never risk more than 2% per trade.
My takeprofits can be moved to breakeven or to longer target depending on market trend.
My system doesn't change over the time because it uses deep price action properties which never change despite of the market conditions.
