The best forex strat to start with would be your own.
My advice to creating your own would be learn price action, learn how the indicators work, what they are telling you and go from there. This is the only way you will build a strat. Read others strats and play around with them on demo. You will quickly find none of them work for you but for every failed attempt you will gain knowledge on why that system did not work. You will soon figure out the pros and cons of the system. Take the good drop the rest. Its a long hard road your are about to go down. I wish you the best. Please again take the time to learn every indicator regardless if you plan on using it or not. I can tell you I can look at a naked chart but could tell you damn near what every indicator is telling you with out even pulling it up on the screen. I prefer price action. But IMO price action is an indicator in of itself. Any indicator is only as good as its user
again good luck
