Signal Sizer — Lot Size & Risk Calculator for Traders

Turn any Forex trading signal into a professional position calculation in seconds. Signal Sizer automatically analyzes your signals and instantly calculates your ideal lot size, risk exposure, and potential gains.

Signal Sizer supports more than 200 tradable instruments — from major forex pairs to metals (XAU, XAG) and exotic currencies across all continents.

📋 How it works

Import your signal — Paste a text signal from Telegram, WhatsApp, or any other channel. It can automatically detects the direction (BUY/SELL), entry price, Stop Loss, and up to 4 Take Profits. Prefer manual entry? Use manual input mode with dedicated fields for each level.

Review & edit — All values are displayed in a clickable grid. Tap any level to edit it on the fly. The currency pair is auto-detected, with manual selection available if needed.

Set your risk — Use our built-in tactile calculator to enter the amount you are willing to risk. The app automatically fetches real-time exchange rates for accurate conversion into your account currency.

Get your results — Optimal lot size, breakdown per TP, maximum loss, and estimated gains. Copy values to your clipboard in one tap to paste directly into MetaTrader or your trading platform.

🎯 Flexible input modes

Price Mode : Enter entry, SL, and TP prices directly.
Pips Mode : Simply enter the number of pips for each level. Signal Sizer automatically calculates the corresponding prices based on the pair's pip value (JPY, XAU, standard forex), with a real-time preview before validation.

⚙️ Advanced lot sizing strategies

Choose your preferred calculation method:

SL-Based : Lot size is calculated from the distance between your entry and your Stop Loss. The wider the SL, the smaller the lot to respect your risk amount. Ideal when your signal includes a defined SL.

TP-Based : Lot size is calculated from the distance between your entry and your first Take Profit. Useful when trading without a Stop Loss or when you want to size your position based on your profit target.
For each mode, choose how to split your lots:

Equal Lots : Same lot size on each TP level. Each TP yields the same gain.

Weighted Lots : Lot sizes are distributed proportionally based on each TP's distance. Closer TPs receive a smaller lot, farther TPs receive a larger lot. This balances the risk/reward of each level.

Custom Lots : Manually define the risk or target gain amount you want to allocate to each individual TP level.

Manual SL : Even without a Stop Loss in the signal, calculate it from the risk amount you are willing to accept.
