So this one looked like a bug, but it isn't really - upon further investigation - so I'll just share it with the community here:
I made a couple of purchases here on SM yesterday in two speccy companies that I am interested in (but do not hold any of each yet with real money), BML (Boab Metals) and PGO (Pacgold). I also bought a little more BML today, however I noticed that the two trades went through at different prices despite Commsec saying that BML closed today unchanged at $0.635.

Here's my trade details here on Strawman.com:

That's wrong I thought, until I checked the ASX website, which has a current graph for BML that says that they did close at 65 cps yesterday and dropped -1.5 cps to 63.5 cps today - which aligns exactly with the trade details here on SM:

Here's that same graph on the Commsec website:

It looks a lot different but that's mostly because it's been compressed into a much smaller graph in terms of width. Both Commsec and the ASX have rounded 63.5 cps up to 64 cps for today's close on their respective 3 month graphs. And both graphs suggested BML dropped a little today, even though Commsec's trading data suggests they closed flat because they have the wrong closing price for yesterday. Commsec's graph data doesn't align with their trade history data. I would imagine that the ASX is probably going to be more accurate and the ASX data is the same as the data here on SM, so S&P have probably got it right and Commsec have stuffed up.
I have come across similar scenarios before and assumed it was a late block trade or a Cboe (Chi-X) trade that Commsec didn't pick up, but whatever it is, there are sometimes discrepancies in the closing prices of smaller (mostly nanocap) companies with Commsec which is the trading platform I use most because I am so familiar with it and find it so easy to do basic historical research with - but we must not assume that the data we're looking at on our trading platforms is always 100% correct, coz sometimes it's clearly not.

@Strawman Please add CCL (Cuscal).
It is an interesting stock that flopped at IPO
I looked at the prospectus and it is just too much for me. Will let someone with more time and interest in the card payment sector read over the 500 page prospectus.
When you hit save after spending a substantial amount of time writing a post (about 10 minutes) the post does not get created and I go back to the main page without anything saying the post got saved or created.
Then I have to go back and write it again.
Or maybe it's just me... :(
Hi @Strawman I noticed that Damstra ($DTC) has been delisted since April after takeover but it is still showing in my portfolio instead of being turned to cash.
