Adding Licensing to an Indicator

MetaTrader does not let indicators connect to the internet, so indicator licensing works through a small companion EA, the FXNook Agent.

Step by step

1. Make sure the product type is set to Indicator.
2. In EA Licensing, download the licensing file. The page only asks about OnInit, and Old-style code for MT4.
3. Add the include line as the first line of your indicator and compile.
4. From the same page, download the FXNook Agent and compile it once.
5. Put your compiled indicator and the compiled Agent in the product ZIP you upload.

How it works for the customer

• The customer runs the Agent on any one chart with their key.
• The Agent checks the licence every 15 minutes and saves FXNook’s signed answer.
• Your indicator reads it about once a minute and checks the signature itself with your secret.

The same Agent works for every FXNook indicator, holds no secret, and never trades.
