TZOR, are you sure it was a put $15,- buying order ?
In this message you write 'selling at $7,20'.
The seller of the put, can be everyone, gets the premium of $7,20 now
Needs a litle money for margin maybe but RECEIVES THE $7,20 now.
When the pps reaches $15,the premium is earned.
So this WRITING, put strikeprice $15, acts almost as a buy
future at this level.
Just an idea.
Greetings.
