SignalSizer reads a signal channel, sizes every trade so a stop-loss can only ever cost profit above a protected capital floor you set, and places it on MT5 in one click — or automatically, if you choose.
Free to try · PRO from £49.99/year

Installs to your user profile — no administrator rights needed. The setup wizard walks you through everything below on first launch.
No admin prompt, no elevation — it installs entirely within your own Windows user account.
Works with any broker's MT5 terminal. If it isn't installed yet, the wizard downloads and launches the official installer for you.
You'll need a free api_id/api_hash from my.telegram.org — the wizard explains exactly how to get one, then logs you in with your phone number.
Pick one or more groups/channels to listen to — useful for keeping a test channel alongside your main one. Switch between saved channels anytime from Settings.
Match each instrument you trade (e.g. NAS100, GOLD) to your broker's exact Market Watch symbol — a searchable picker does the rest.
Enter your account login, server, and password — MT5 logs in automatically from then on. Trading always starts against your Demo account for safety.
Have a license key? Activate it here. Otherwise continue with the free sizing calculator and activate anytime later from Settings.
The setup wizard and the trading app itself.
