Hi @CanadianAussie yeah the 2c rule is still on place (you can't buy shares on Strawman for less than 2c).
The reason is that it's otherwise possible to jag huge gains on Strawman that would not be possible in real life -- and it's all to do with what market data we get, which is only end of day.
We do have volume matching for our orders, so if for example you wanted to buy $20,000 worth of a company, and only $10,000 of shares were traded that day, the order would only partially execute, and the remainder would remain pending until enough volume was traded on subsequent days.
That's all good and well, but we only get end of day data. So we know the last traded price for the day, and the total volume traded that day. But it could be possible that a stock opened at $1 with 9000 units traded, and then closed at 90c with 1000 units traded. So in real life, if you had an order for 90c you could only have bought 1000 shares. But our system would assume that 10,000 shares traded at 90c as that's the data we get.
This isn't really a problem for the vast majority of shares, but when you get to super illiquid nanocap stocks, it becomes a huge problem.
Some clever cookies figured this out during the competition and were recording gains that were completely unrealistic. Basically buying much bigger volumes than weren't really possible. And flipping it for big profits if the price went from (say) 1.1c to 1.5c the next day.
Anyway, that's the background and hope it makes sense.
