Plan the trade. Size the risk. Follow your own rules.
Pecunie turns an entry and a stop into a share count that respects the limits you set. Then it keeps the record of what you planned, so you can see whether you followed it.
Three decisions, in order
Write the rule
Entry level, stop level, targets in R. A thesis, and the condition that would prove it wrong. A plan you can't state isn't a plan.
Let the stop decide
The distance between entry and stop sets the share count, so every position risks the same fraction of equity no matter how wide the stop is.
Keep the record
Positions are tracked against the stop you committed to, and every adjustment is logged. Adherence becomes something you can look at.
Total open risk across every position, against the cap you set. It turns amber before it turns red.
Size a position now
This is the real calculator, running here. No account needed.
Widen the stop and the share count falls. The dollar risk stays where you set it — that's the whole idea.
What Pecunie does not do
Being clear about this is part of the design.
No recommendations
Pecunie never suggests a trade. It reports what your own rules produced, and nothing else.
No signals or predictions
There is no model forecasting price here. Your rules are evaluated against market data — that's the entire mechanism.
No celebration
A winning trade updates the table and nothing more. Celebrating outcomes trains exactly the behaviour this tool exists to correct.
Start with your risk limits.
Set your equity and your maximum risk per trade, and every plan you write afterwards is sized against them.
