The secret of trading is to understand what the signals are telling you, and that is why I emphasise that you should use your eye, most of all, and just a few tools, otherwise you get lost in all that gobbledegook and never see the wood for the trees.
To become proficient and confident in trading, you need to practice, and only you can do this for yourself. I suggest trying out the several indicators that I have explained, one at a time, and see how it fits to the way the price moves. There is no holy grail, although with each improvement and complication in indicators, some people would tell you otherwise! The fact is that you just need to have your wits about you, and not get stuck in being a slave to any particular indicator. Some work better in different sectors, some better in a strongly trending market than a weak trend, and some better when there is an ‘r’ in the month (joking, I just made that one up, although sometimes you may think it’s true!).
You should see a general agreement, but don’t expect anything to work all the time. You need to have self-control and apply good money management techniques, and you will find that you too can make a profit.
