You don’t need to wait until Q2 filings to see how much dilution (if any) is going on.
Look at the SP volume. If you see more red / green than blue, then someone is selling.
Then look at the L2 to see which MMs are on the Bid / Ask. If it’s one or more of the known dilutiors, there you have it.
Note: some of the MMs can be sneaky. And will pass the trade as a buy (blue). These are also easy to spot, as heavy blue days with no noteable increase and the known MMs on the Ask are a clear sign.
Also keep an eye on short volume. Last time I looked at OMVS it was near zero, but always check it.
