Yes, they did trade as high as 5.6c today and as low as 5.1c - and they closed at 5.4c. I'm not sure what any of that tells us other than there were more people wanting to buy OSL shares at higher prices than there were yesterday - probably because they attribute some weight to the director buying shares. The stock will trade higher whenever there is any news that is thought to be positive, and they will trade lower when there is any news that is thought to be negative, or (I would suggest) when there is no news at all. Looking at their trade history since the big announcement on the 25th March, apart from the following day - 26th March - when they closed up 0.2c (up from 4.9 to 5.1c), they have closed lower on each of the subsequent days (27/3, the 28/3 and the 1/4) in which there was no announcement from the company on that day. They have risen on the two days when the company did make an announcement (29/3 and 2/4 - today) that has been perceived as positive. It looks like no news is not good news if you're still holding OSL. The buyers and sellers (the market depth) has been pretty even in my view, but a lot of buyers and sellers (especially sellers with larger positions) won't bother with limit orders anyway - they'll just wait until they see a price they can live with and they'll make their move. You won't see that in the depth - only in the traded volume.

When I posted above at 11:52am that I expected them to touch 5.4c at least, I simply meant that I would be surprised if they didn't trade at 5.4c shortly after I posted, or higher, because they were at 5.3c and the lowest offers were at 5.4c at that time. Not surprised they traded up to 5.6c, or as low as 5.1c. Still won't be buying back in though. One director buying $20K worth of shares doesn't mean much at all. It doesn't change anything.
