Practical tools

Tools built around the process.

Built for decisions that should be calculated, not guessed — from individual trade planning to deeper system analysis.

I built these after watching the same mistake happen with different tickers: a position sized off a feeling instead of the stop distance, a trade taken because the reward looked good with the risk never actually measured. None of these calculators predict where a stock goes next — nothing here does that, and I wouldn't trust one that claimed to. What they do is take the numbers you already have — entry, stop, capital, your own past trades — and turn them into the trade-off you're actually making, before you make it. If a result changes your mind about a trade, that's the tool working.
