Ha, honestly it takes years to learn. I lost so much money along the way from bad advice and listening to retards.

You don't need signals. You need to learn to read charts and exercise patience. I primarily use fibonacci extensions/retracements and trend lines, which are predictive rather then lagging indicators. As with everything, the trick is to keep it simple. There are many ways to analyse and profit from trading, but this approach works for me.

The number one thing you can learn is patience. Removing emotion is the single best thing tool you can have in trading. The second best is ignoring the majority, because they will almost always be wrong.

It really is as simple and buying low and selling high, but you need to pick a few charts and study how they move, start with small amounts and always take your time. This works on shorter time frames too, but the risk is increased exponentially, which is why I trade on much longer time frames.  If you buy something low enough, then your risk/reward is minimised and all you need is time to wait for it to move in your desired direction. 

As with most things in life, you will need to invest both time and 
money in order to gain experience and confidence.

I would recommend learning about trend lines and fibs. Anyone who can teach you about the ABCD movement of a fibonacci sequence should point you in the right direction.
