Yes, candle-based data tell you so little about the ticks movement, so that's why backtesting with tick data is highly essential. As you're not a programmer, you have limited choice on tick backtesting and improving your own systems.
For instance, you may backtest by using backtesting suite such as WealthLab at
www.wealth-lab.com, or you may ask someone to assist you; Fabrefactum.com will backtest your system at a cost. I'm thinking about helping you out to backtest the systems, but i'm afraid that i'm now a bit busy in finishing fxfisherman (just a little bit to go, we'll make it).
I have a few years worth of EURUSD ticks on fxfisherman.com. PM me if you wanna download it.
