Course of sales for MAD for the last few days.
Note the instant tick down as soon as a buy takes place exactly the same time or one sec after.
As soon as they tick it down they load the next two sell levels instantly with small orders.
Short sellers? ,no short reported from the ASX.
Now why are they doing that on a stock with a market cap of 25m that trades no more that $10-$30k a day.
Maybe someone can explain why. All I see is that it brings out more sellers.
And on Friday last trade at 5.3, in the last min they sell 6522 shares at 5.2 and then 5393 shares at 5 which
made the 5.3 seller come down to 5 and still sitting there this morning.
