Selling an EA Shouldn't Mean Giving It Away.
One customer shares your software with a Discord group. Five people install it. Your revenue stays the same. LicenseFort gives every customer their own controlled license — reducing casual sharing and unauthorised reuse.

How It Actually Works
No manual API integration for MT4/MT5 — the Protect Software wizard does steps 1 and 2 for you.
- 1
Upload your EA or indicator to the Protect Software wizard and pick MT4 or MT5.
- 2
LicenseFort inserts the license check and compiles it for you — download the ready-to-ship file.
- 3
Generate a license key, optionally bound to a specific MT4/MT5 account, device or expiry date.
- 4
Send the compiled file and the license key to your customer.
- 5
Your customer enters the key once, in the EA's Inputs tab, when they attach it to a chart.
- 6
LicenseFort validates automatically from then on — no server for you to run.
- 7
Revoke or let a license expire, and access is denied on the customer's very next check.
Watch the Wizard Protect a Real File
Every screenshot below is the actual Protect Software wizard, running — not a mockup. This is exactly what you'll see after you sign up.
Step 1 of 6
Pick your platform
MT4 or MT5, EA or indicator, or a Windows .exe. This decides which compiler and file type the wizard expects next.
Attention! MetaTrader blocks outbound requests by default. The first time a compiled EA runs, it may prompt for your LicenseFort validation URL to be added under Tools → Options → Expert Advisors → "Allow WebRequest for listed URL". It's a one-time setting per install — the EA's own error message walks through it if it's missed.
Building Something the Wizard Doesn't Cover?
For Linux/Mac software, browser extensions, web apps or your own backend, call LicenseFort's validation endpoint directly with an account API key — the same endpoint the wizard uses under the hood, minus the automatic MQL insertion and compiling.
Replace YOUR_LICENSEFORT_URL and the API key below with the real values from Dashboard → API Keys.
var client = new HttpClient();
client.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("Bearer", "sk_live_YOUR_API_KEY");
var payload = new { productId, licenseKey, hwid = GetHardwareId() };
var res = await client.PostAsJsonAsync(
"https://YOUR_LICENSEFORT_URL/api/v1/license/validate", payload);
var result = await res.Content.ReadFromJsonAsync<ValidateResponse>();
if (!result.Valid) {
// deny access — show result.Error to help support, not the end user
