Thanks for the explanation. Looks easy to follow. Yes. Sigh.  ???
I started here with nothing and still have most of it left.

Thanks for the "dogs breakfast" explanation - too many years ago that I dabbled in SQL to check your coding - so accept that your intent is still honourable.
Your "system" is still malleable in the sense that I can see on my live prices that a certain share has increased in value over your 15 min delay prices and can then buy on your system and as such get the benefit of the "delay" between pricing - I am sure I could do the converse with price falls - but then I would in essence be trading rather than investing - which to my understanding is what the competition is all about
Maybe consider restricting frequent buyers/sellers to remove the trading aspect from the competition - just a thought

You are a brave man posting site code with db statements constructed using simple concatenation.

1=1; drop ... and all that.

Shouldn't - use it as a frame of reference when you rewrite O:-)

I was also under the impression we wouldn't be able to conduct ourselves as traders but as chairmen of investment clubs. When I ran our office competition I had rules to exclude traders.

The live pricing advantage is killed off by the pending delay. You might think you can see the future using your using account, but then your price is adjusted to the actual live price when you purchased.

if you'd like to see it in action take note of the live price on your next purchase here.

I had to change my security question, too many bots getting through. What do you think of: When something is really nice, in afrikaans we say "Dis baie l****r"

Nah, multiple questions and you give a random one when he signs up.

I would load that question and its key via an Ajax request and generate it client side plus a honeypot. So you'll end up with:

input 1, hidden, name="questions"
label, question text
input 2, name="answer"
input 3, hidden, name="telephone"

Reason:
1. It is generated client side so bots must support JavaScript
2. Random question so difficult to specifically target you
3. If that honeypot (telephone) comes back with a value you know a bot entered it

...or just use Google CAPTCHA
