I like the way you are thinking, I wan to addt a few things to be known.
Forex is like Poker. Only a few people (less than one on 20 players 0,05) can understand and win at Poker
Programming an EA is not too much difficult. By programming w/ a computer, you can send an object on the moon and make it landing w/ an error less than one second.
You just talked about indicators, but those indicators can not bring correct values to the fact, there are too many unpredictable events during trading hours. It's like when you crash a disc. It becomes quite impossible top hear music if your CD is crashed.
Another point: SL and TP are visible to trading computers that like to eat all stops like Pacman w/o giving notice.
So, suddenly you can see some indicators values raising w/o clear explanations and showing wrong directions because a bank directors got a big finger. And, when you want to predict the future, the prediction are always based on wrong values from a (sad) past.
So... Is there a way to think better ?
My Answer is YES
If you want to associate your ideas w/ mine, we can build together something simple and satisfying working on trending or not.
