Demetra Precision Lot Real Cost Lot Size

Precision Lot gives you the lot size that keeps your real loss at the stop within your risk. Besides the stop distance it counts the live spread, the slippage you really got on your past stop-outs, and the commission.

What you get

- Drag the ENTRY and SL lines on the chart, or use a fixed stop or an ATR stop.

- The real-cost lot next to the textbook lot, so you see the difference at a glance.

- Your own costs: stop slippage and commission measured on your closed trades. Until you have history, your input values are used.

- A lot ladder: the lot for ten stop distances around yours, at the same risk.

- Never rounded up: it uses your broker's lot step and says BELOW MIN when the risk is too small for the minimum lot.

- Margin needed and free margin left after the trade, with a NO MARGIN warning when your free margin cannot open the lot.

- Prop-Safe mode: it cuts the lot so that one stop-out cannot break your daily or maximum loss limit. Losses taken earlier today and account credit are counted.

- The panel folds on a small chart, every line has a tooltip, and the lot can be selected and copied.

Good to know

- The prop day starts at broker midnight by default. You can set a fixed UTC offset instead; change it yourself when the clocks change.

- On live charts it never places, changes or closes orders. No DLL, no web requests. In the Strategy Tester it opens one small demo trade so the Market validator can check it.

Trading leveraged products carries a high risk of losing money. Precision Lot is a sizing tool: it does not guarantee profits and cannot prevent losses. Test it on a demo account first.
