This is the most important thing of Forex trading

A good Stop Loss setting is the most important thing of trading system. Why ?

Let's say you have init balance 1000USD , you entry a order and lost -50% , then you left 500usd only , which mean you have to make your account increase 100% to recover to 1000USD ( 500 * 200% = 1000) .
This is harder then you lost -50% , the piont is that you should stop your lose as good as possible, the balance you lost more , the much harder you recover.

It's not saying that a small range's StopLoss setting is the best, if the stop loss level set to too small, your position will be easily hit by the market move , especially when the data/news come out.

So, how to set the best stop loss level ? There're some base ideas:
1. use recent Support level or Resistance level
2. By Boll band up/down edges.
3. By trading volume peak
4. By AI model (we will show next article how to)

When you day AI model, do you mean an EA?

Oh it will be fun to see that the AI model is chat gpt. Lol.

Would like to add that all traders want to make as much money as possible trading forex, but focusing on monetary goals alone can make it more challenging to become a profitable trader.
