All calculators
Fourteen tools, no sign-up. Eleven of them need nothing but the numbers you type; the rest prefill a rate you can overwrite with your broker's own.
Risk
Before the trade: how much to put on, and what a bad run looks like.
Trade
The trade itself: what a pip is worth and what the move paid.
Levels
Where the market might turn.
Account
What the broker charges and what the account is doing over time.
