Carry on studying and demo accounting, before you get to the end of your studies you will probably chop and change your ideas anyway.
Personally, id go for something simpler, possibly no indicators at all or maybe just one, a Simple Moving Average.
End of the day, its whatever works for you
Congratulations Klairehiro finish the school and keep demo trading , many new traders stay demo trading for at list 3 months which i think is good. I think , then start with a Micro acct and start with a .01 pip value to have some skin in the trade, because now you put allot more attention on what your doing . Its a psychological thing.
The only way that anyone can really answer this question helpfully is by backtesting it over 400-500 trades, and that’s really what you should do, yourself.
I agree with Eddie, really, and would go for something simpler without the indicators.
That said, I must say that as indicator-based systems go, I’ve certainly seen a [I][U]lot[/U][/I] worse, and my own guess is that it [U]might[/U] be tradable, with patience and discipline. I wouldn’t be astonished, anyway. And all anyone here can do is “guess”, you know, without backtesting it?
