I think the trading platforms earn more money if you make more trades. So it's in their interest that you trade for as long as possible.

I read it does exists trading platforms were if you earn money they lose it because they launched the order internally between their affiliates, and not to the external trading networks (or whatever they are called). This if they even really launch the orders...

We can not see the traders' internal code so anything can happen. I think they look like money-collecting machines. Take care guys.

Edit: Wow, that downvote sounds very interesting, as the first that I pointed is widely known, the so called "Market Makers".
