This is something about Trades Management (How to manage your existing position)
1. If the trade went well ( You are in profit ) , When Reward / Risk Ratio hit 2:1, Close Half position. (You can also close all, if you feel good enought to take all the Floating Profit, but you will have the opportunity Cost of not be involved in the next trend , Hard to decide? Then Close Half! )
Why? Coz by doing this, even the market goes back and hit your SL, you are still winning?
Calculation:
0.5 * 2R - 0.5 * 1R = 0.5 * R , If R is set as 2% of your capital,
then Minimum Result it 0.5*2% = 1% (Congratulations! Now you have a 100% Winning Trade with 1% Result, and you are still holding half position with RiskFree)
2. If trend is in your favor, and price hit 4:1 or 6:1 , or maybe 0.618 pull back, or opposit Resistance or Support , Feel free to close another half , which is 1/4 position.
3. If hit 8:1 RR, close all profit, or Move SL to the latest Pivot to trail your profit.
You can use 8ema or 21 ema to trail as well. or close all profit when you see price action shows reversal pattern .
