All of this is of course patently false. Be aware worik and others will try to keep you from joining markets under dubious pretenses like protecting you or caring about your individual financial sanity. Don't listen to anh of them. Don't gamble more than you can afford to lose and you shall be fine.

Stay out of those markets.

Here is a thought: What paid for all those shiny towers in Wall Street? Transaction costs from people "...joining markets".

Have you heard the joke about the customer's yacht?

Lots of those shiny towers were built by wide bid/ask spreads.. now a days liquid (good markets trade) proportional to stock price to basically pennies.

I do agree I wouldn't join an automated trading platform without a high level math degree and market understanding though.
