What is the best trading forex system of all the time?

Google it. You’ll find all the info you require.

Logic and not being emotional about the money I am risking when I trade would be my answer. I know that’s not a specific system, but would it even be possible to quantify one system’s performance versus another’s, realistically???

Awesome point. I think it’s impossible because of everyone’s individual emotions along with experience.

Sell high - buy low is much better. Gravity and all that.

Know your charts, look for SNR, draw your trend line appropriately, look for Divergence, wait for break out, entry when there is pull-back…still market is unpredictable, especially around major news, but, the rest of the charts should be trad able…and profitable…

My setup is simple, EMA4, stochs/ADX, wait for price break from below or above, when the candle close, entry according to price movement. Close bull, BUY, close BEAR, sell… Take profit 50 to 125 pips. Stop Loss…previous low or high. Good luck bro…

A system is steps you follow in your trading for example, mental rehearsals of scenarios to expect in your trading day. What time you sit at the computer or go to the trading floor, markets you look at before you start executing, etc. In an organised manner, this is a system, much different from trade strategy.

The best system is the one that gets you making money.

Good point, emerald… Like PipNRoll once told me, a system and a strategy are very different (yet correlated) things…

Knowledge and Preparation that puts the balance of probabilities on your side so that your short term success add up to be long term successes. There are thousands of systems available to traders from free to several thousands of dollars and traders still fail. Knowledge and preparation is what makes a system into your best system.

It’s not just about the tools…
