I had a look at the leaderboard and have a question of Patrick - the best performer on the board when I looked was Ashburton Inflation ETF (ASHINF) however these units were purchased at 8:23:52 on 2018 - 01 - 02. The market doesn't open to the public until 9:00:00 and only the auction is open and that is exclusively to brokers and opens 10 minutes before public opening. So how was it possible that the holdings were acquired prior to even the auction period, and, further, what price was inserted against the purchase of these units - was it close of business 2017 - 12 -31, or was it based on some or other factor
Please clarify
Thanks

It's easy, my cron job for adjusting pending orders into actual orders doesn't kick in until 9am, that's the price they should have been given

I can explain it in robot


Highly dodgy code was here 



 

Basically after 9:30 update any orders made since 5pm last night with live prices. This fixes overnight orders and also updates daytime orders with actual live pricing, so nobody can cheat using their actual brokerage account. Sadly I didn't have the date updating, there's always a bug somewhere! I'm sure all the php experts are going to chime in and tell me how I'm using old SQL and that my code looks like a dogs breakfast, but hey, it gets the job done!

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 

My paranoid senses went haywire.

Exploits everywhere

Lol, I know, I know. One day when I don't have a day job I'll rewrite it fully. Post will now vanish

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

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.

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