@Sparklez:This feature via Tiger Broker platform has really given me great opportunity and I did not realised until I checked my filled order.Attached is an screenshot in regards to yesterday stock movement for $Snap Inc(SNAP)$so as you can see, I have decided went on an short position Snapchat at the price of $36.50 and initially I just wanted to cover my short position at the price of $36.20 [Bless] However, the system filled my short position at a better price for $35.96. This feature has allow me to build my cash flow even more and I am greatly thankful! Has anyone occur this before? This is a subtle feature and yet great opportunity for us investor's to earn extra cash [Eye]
