Small calculators for the parts of trading that are arithmetic, not opinion. They run entirely in your browser — no sign-up, no account, nothing you type is sent anywhere or stored.
Why these two first
Because they answer the only two questions that decide whether an account survives its first bad month: how big should this position be, and how much damage can a normal losing streak do? Everything else — entries, indicators, timeframes — is downstream of those.
The reasoning behind both is written out in the Learn section. Read the lesson first if a number surprises you.
