Nadine,
I know exactly how you feel !!
I am reading and using Fibonacci-ratios.
And also Gann.
And a couple of my own strategies.
The problem you may be feeling is when you are following one system, and then you have a drawdown. And you say to yourself, "if only I had been following that other strategy, I would have made a profit".
But, follow Fettered-Chinos advice, and trade your 3 or 4 favourite systems in parallel.
This is what I am doing !! ( mainly MAs, Fibs, CCi, and 2 of my own ).
What you will find, is that they will have their ups and downs.
But, over an extended period of time, they tend towards the same amount of profit !!
Then, you can prove to yourself that any system can work, as long as you get out of your system the "grass is greener with another system" mind-block.
Then you can settle on a system that suits your personality.
Hope this helps, and good luck.
