Short pieces on the arithmetic behind trading results. No strategy internals, no predictions. Every figure here is computed from the numbers shown, so you can check the work.
Risk
Why a 20 percent drawdown needs a 25 percent gain to recover, a 50 percent drawdown needs 100 percent, and what that asymmetry means for risk limits.
Statistics
Profit factor is a ratio with no units. Two systems can share a profit factor of 1.5 and net $2,000 and $3,200. Expectancy times trade count is what pays.
Risk
Position sizing decides survival more than entries do. A worked example of identical trades at three risk levels, plus how long a losing streak to expect.
Execution
Spread, slippage and commission are a fixed toll on every trade. How that toll scales against target size, and why it decides which strategies are viable.
Method
What to check on a published trading record: verification, deposits, drawdown against gain, sample size, and how much of the profit came from one trade.
