Thought of brining weather data into Amibroker. Googled for free weather api data. OpenWeathermap came to my notice. Using Openweathermap one can get weather data for any location on the globe immediately.
Sample Weather Output

Amibroker AFL Code to get the Weather Dashboard
Code requires Amibroker 6.17 as some of the new AFL functions like InternetClose( handle ) , InternetOpenURL( “url” ) , InternetReadString( handle ) – which is essential to read from internet resource/http api is available from v6.17 or higher version.
