Theoretical trading system

[IWannaBeAMillionaire]

Hey all. If someone had an endless pot of money and started with a small long trade on the S&P, say £1 a point, then when the trade goes against him, open another to average down at a gap of say 100 points.

Could this person not always win in the long run?

There's a similar strategy in traditional gambling called a Martingale
