YSP: Discount to Net Asset and Turning the Corner

I don't had level 2, but ADFN is reporting 29k sell, 55k buy's at last reported trade (11:35). i.e. almost twice as many buy than sell orders. sellls are all showing up as smal;l individual trades (e.g. £1k or less), buys are mostly of larger quantity, although largest only 10k. Given the significant ex div induced drop, & tendancy for small PI's to panic or at least lock in profits, this suggests concerted accumulation at an attractive level.
Whilst the directors buy was modest, I still view it as a strong hint, I am sitting tight!
