Quote from NoDoji:
Here's how to judge your performance:
You've been consistently profitable over two years of trading.
Did you attain this profitability by following a specific trading plan (business plan) with very few rule violations and is your profitability in line with the results your business plan predicted? If so, then your performance is excellent and you can comfortably size up and increase your returns.
Did you attain this profitability by using leverage itself as an edge (averaging down until positions eventually became profitable), or by cheating (violating your rules, but somehow coming out OK in the end)? If so, then your risk of ruin is high despite your positive results so far.
Are the returns over these two years significantly less than your trading plan predicted? If so, then either your trading plan cannot withstand varying market conditions or your ability to follow it is poor.
Only you can judge your performance.
