Twelve trading calculators
No account, no email, no limit. Each tool shows the formula it used, the assumptions it relied on, and a worked example you can check by hand.
Forex position size calculator
Work out the lot size that risks exactly the amount you intended.
OpenPip value calculator
What one pip is worth per lot, in the currency you choose.
OpenRisk to reward calculator
Compare what you stand to lose against what you stand to gain before you enter.
OpenProfit and loss calculator
The money result of an entry, an exit and a lot size.
OpenCompounding calculator
What a steady percentage would build over time — as a projection, clearly labelled.
OpenEconomic calendar
Scheduled releases by currency and impact, from recorded rows only.
OpenDrawdown calculator
How far an account has fallen from its peak, and what it takes to recover.
OpenMargin calculator
The collateral a position locks, and the leverage it implies.
OpenLot converter
Standard, minor, micro and nano lots in units of currency and pips.
OpenRisk of ruin calculator
The modelled chance of losing down to a stated floor.
OpenTrading session clock
Which sessions are open now, in your timezone, including overlaps.
OpenForex trading time converter
Turn a session time into your local clock without arithmetic errors.
OpenWhy the assumptions are printed
Spread, slippage, leverage and the pip convention you pick change the answer more than the strategy does. A number without its assumptions is a guess with decimals.
Why there is no live price
Any quote we hardcoded would be wrong for your broker and stale within seconds. Where a conversion rate is genuinely needed, you enter the one your platform shows and the result records that you supplied it.
Contract specifications
Pip size, contract size and digits come from one published specification table used by every tool and the tests behind them.
