You understand that results from 18 trades have no real statistical significance, right?
When you have the results of 1,800 trades, you have something to look at and analyse.
This is part of the problem of a 4-hour chart system that trades once every 6 weeks.
It might work. It might not. It’s going be terribly difficult to tell which.
But you need to know first, so you can make an informed decision about what to do when it has a 6-month losing period, because this system, whether it has a real edge or not, WILL have a 6-month losing period at some point.
All Fib levels are arbitrary anyway. Fib levels aren’t real. That doesn’t necessarily make them invalid or a loser, it’s true. Millions of people believe in the I Ching, and thousands of people trade according to the phases of the moon (honestly, they do) and some of them swear it’s profitable. I’m not advising you to use Fibonacci, or not to use it, just to appreciate if you want to use it, that you’re using something which has never had any real, mathematically valid evidence for it published, other than anecdotal stuff produced by its own enthusiasts.
I wince when I see people wanting to trade and wanting to make money from it, however modest and sensible-looking their ambitions, when what they’re asking for advice about is something based on “moving average crossovers” and “Fib levels”. Everyone starts off in this business with the odds against them, and these two parameters just aren’t things that will help to get the odds in their favour.
