Who supplies the trading platforms for these online trading scams?

There are many technology companies who are providing online trading platforms. They are benefiting from the profits generated from these scams as well. The price feeds may be real – but for the most part the trades are not being “passed” into the market. Binary option, forex and CFD scams operate like a Casino – all the trades stay in the house.

Are the trading platforms manipulated in order to force losing trades.

Of course.

Are there any trading platforms one can trust online?

The only platforms that are safely not rigged against the trader will be those used by only the most professional traders, in very regulated jurisdictions such as in the US and Europe. Always take council from the home regulator as to who one can trust.
