Hi. I have developed many automatic trading bots both in Forex and cryptocurrencies.
Unfortunately, Plus500 does not have an API, so things should be done by sending mouse clicks and keystrokes to the browser. Not an elegant solution, although it works. I made such interface for eToro (also has no API, also CFDs) and it worked for me.
Have you considered the possibility to trade in a site that has a programable trading interface (MT4, Ninja trader, etc) or an API REST, like most exchanges have?
What instruments do you trade?
