trading system sharing

Hi all,
as a junior to Forex Factory, I'm unable to write in Trading System forum. so I write it here while I think it's more related to that section:

I'm studying and demo trading for couple of years, have experience in stock markets for 10 years and I have my live account for a month.

the trading system I considered winning during back testing and demo trading isn't that good in live action. I share it here with you:

I simply go long if:
My SMA5 crosses above SMA10 (I use SMA50 to find the long term trend also) And Stoch is headed up, not above 80% And RSI is more than 50

I look at H4 for finding the overall trend and trade in M30 I enter when candle closes (apply on new candle) My S/L is the below support or resistance level or PP My T/P is above S or R or PP

can you comment on this plan?
I appreciate your advices and comments.
regards,
Emad

This sounds like a pretty solid system. One of the first systems I first traded was a MACD, stochastic and moving average system. It paid the rent.
