The data doesn't say much, so far shows only the issue with the two time periods and the difference in profits, I was trying to "catch" them by noticing leaked statistical ambiguities in their numbers, there is no statistical indication that the numbers are cooked, but I was also unable to identify the method they use for profit-taking. It looks like they bet on price changes with open short or long positions (like forex) and they sometimes close on a profit or loss when the price moves rapidly. This could be made by a simple automated bot, 24/7, no need for hired day traders, but I digreess.

While customers might be misled into believing they get higher profits (more than 1.3% on average), they can check the calendar and get an idea of what the profits would look like.

That's very nice of them, but with greater stability comes greater loss of profits. I personally would design my service to have better average profitability and mask variance by carrying results from the previous day (like mining pools operate). This would give the same profitability as the previous period while preventing negative days.

Anyway, my position stands as before, I can't tell if the operation is honest or if it's a ponzi. It matches real trading more, and it would require greater difficulty to operate it as a ponzi.
