I'm am not sure what is going on here.
The volume was actually the second highest traded volume for the year.
Although the intraday volume that triggered the spike down was not large.

Its impossible to see behind the veil of the warrant issuers to see if they have a motive to trigger stop losses.
However generally speaking all Minis are covered by stock held by the issuer.
In my experience as soon as I place an order for the warrant I can see on IRESS real time depth an equivalent volume of the underlying trade immediately.
So the only profit the Warrant issuer should make is on a slight edge on the buy sell spread and on the daily interest charged on the loan. The fact a stop loss is triggered will cause a spike down on relatively illiquid stock such as SRX as their bots sell the covering underlying stock at whatever price is available. The warrant holder is only refunded the average achieved sale price (less the strike price) so the downward spike is immaterial to the issuer.

I may wait a bit before getting back on the horse.
