With QCharts - is there a way to determine whether a trade is a buy or sell ? It's obvious for the trades that are made at the bid or ask. But what about trades made between the bid and ask ? Also - I've been following a small wireless stock (WLGS) - and there have been some large trades occurring consistently after normal market hours. Example - on Friday 16 FEB 01 there was a 620,000 trade at 4:09:34. Was that trade a buy or sell ? Any clue why such large trades are occurring consistently after normal market hours ? TIA.
