SO MUCH DERP. Jesus.
I'm going to leave aside the "everything is fixed" whine and just say that if you really think the markets are rigged against you, you shouldn't be trading in the first place. (Also, "waah the big bad banks rigged the market against me" is usually code for "I made stupid mistakes and lost all my money and I don't want to admit it's my own dumb fault".)
But I want to latch on to this:

Anyway there is nothing wrong with the method you described? Isn't that how big institutions trade? Because they have the capital? With that large of a capital and small bets and an automated process, this is almost a sure win method as long you can find someone that lets you bet like that. The key is to be patient and don't be greedy.
Absolute crap. If any trader at a "big institution" tried implementing a strategy like what Hognix described (and that you can't find a problem with), they'd be fired on the spot for being stupid.
The reason they'd be fired for stupidity is that the strategy is guaranteed to blow up - and the reason the strategy is guaranteed to blow up is that your bankroll isn't infinite. To leverage off Hognix's example, let's say you're betting on GBPUSD, and you double your bet every time you get it wrong. Doesn't matter if you're betting long or short or whatever. If you start with a $1 bet, and you get it wrong 20 times in a row, you'll be flat broke.
This is not me wanting to rain on your parade. This is math.
I've lost count of the number of people who've come through this forum with a "sure-win forex strategy", been told "don't do it it's a martingale", then come back three months later crying their eyes out because they've blown up.
My favourite was a kid (he can't have been more than 20 or 21) named Desmond Leong who came through here in 2010 claiming that God was telling him how to trade spot gold. His strategy was a martingale and we told him as much.
He raised $100k for his "managed fund" from friends and family; three months later he lost the lot.
Update: That all said, I'd like to see your backtesting results. PM me if you want me to take a look and see whether what you've got is the real thing or a dangerous blowup machine.
