IB called to say my Ebay trade before hours on Instinet of a buy of 100 shares for $54.00 was being disputed and would I accept a bust. I refused having sold 2000 at 53.50 the day before before hours to hedge some naked puts. The line to Instinet at Ib had been down and my order that was light blue was held on the IB server until the line went back up and was immediately filled. Apperently the trade is going to arbitration. Ebay was 55.00 after hours on friday, exactly at the strike price. Was 56.00 offered Monday morning so I went 54.00 bid. Would you accept the bust or go to arbitration? thanks for any advice, this is a new experience for me.
