Option block orders are large, privately negotiated orders. They're executed apart from the public auction market.
我通常會跟呢種Type
因為我覺得呢D通常係大戶 長線投資
*************************
Orders marked SWEEP are multi-exchange sweep to fill orders.
SWEEP 既話 因為佢地要係短時間咁fulfill 晒全部order 所以通常有大事即將發生 D人係度追貨
*************************
Orders marked SPLIT are single-exchange sweep to fill orders.
SPLIT 我通常唔理
