TradeCalcSuite is a personal tool I built for my own trading workflow. I got tired of switching between spreadsheets, broker tools, and half-broken web calculators mid-session, so I put everything I actually use into one place.
There's no account system, no backend, no analytics on what you type. Every number you enter stays on your device. The whole thing runs as static HTML — there's no server reading your position sizes or account balance.
The tools cover the maths I reach for most: position sizing, risk/reward, average down, break-even after fees, compounding projections. A few of the calculators are more for fun (looking at you, Copium Matrix) but even those have real formulas underneath.
⚠️ Not financial advice
These are mathematical tools, not recommendations. The calculators do exactly what the formula says — what you do with the output is entirely your decision. Trade responsibly.
