Position Averaging Calculator

Calculate the exact entry price or lot size needed to reach your target average — directly on the chart.

A lightweight MT5 indicator that solves a common trading problem: if I add to my position at market price, what volume do I need to reach my target average? Or the reverse: if I want to add a fixed lot size, at what price must I enter?

The panel reads your open positions automatically, displays the current average entry price with a dashed line on the chart, and lets you set a target average. Hit Calculate and the tool instantly returns the required entry price or lot size — whichever you haven't fixed. A dotted target line is drawn on the chart so you can see both levels at a glance.

Works for long and short positions. Supports any symbol (Forex, indices, metals, crypto).

How to use:
1. Attach the indicator to any chart.
2. Press Load positions — current average and total volume are loaded automatically.
3. Set your Target avg price using the +/− buttons.
4. Leave New volume at auto to get the required lot size at market price — or set a specific lot to get the required entry price.
5. Press Calculate.
