Great you have finished the school of pipsology.
The next step is to trade on a virtual account to get the hang of placing orders, stops etc
This also means getting familiar with the system you choose.
If you are looking for a mechanical approach, that is simple, you could check out my blog, tradeneophytes - sorry not allowed to provide the link.
Also I advise taking your virtual trading seriously.
I rarely if ever advocate day-trading but if you want to speed up your learning curve then day-trade your socks off on a dummy account. This will give you a better feel for the market QUICKER , than if you were using higher timeframes.
However, I stress that day-trading with real money is HARD - so if you then decide to go live then use daily timeframe, or at least 8 hours.
Finally I really suggest manual backtesting when you have found something that suits you. Yes, its boring as hell but will also educate you in a big way.
If you cannot manual backtest your system easily, then you know its not suitable for you.
Hope this all helps.
