Consistency ,

is something that tends to be overlooked or misinterpreted into regular gains. You don't need to gain regularly, you just need to gain more than you lost. And a small risk with a larger reward will do that for you. You can lose 8 trades with a small risk and win 2 that will cover them, but only in the same set of rules and over and over again.

It is difficult to repeat the same process for a significant period of time where it would be more evident, because most of us are "human" with the emotions attached. As soon as we see a couple of losses we tend to modify something, adjust, change or listen to others in hope things will go a different way. Trading in hope is a losing strategy.

Stick to your method, test it on a large enough no. of trades with small capital or paper trade, keep a good record of what you tried what worked and what didn't. Be honest to yourself and review them regularly.

In this way you are not only building profits, you're building yourself into a trader.
