Q: Order Fill Limit Order Tips for ETFs. I have been placing limit orders to buy TCSH ETF which is a Canadian money market ETF. I have access to Time & Sales data using TD Advanced Dashboard. It looks like the transaction prices vary between 50.10 and 50.11 with "size" typically 100 to 200. I am not sure if "size" refers to lot size or quantity of shares (maybe you guys know?). I would like to buy 1,800 shares at 50.10. Will I have better success rate if I place multiple limit orders using lower quantities at 50.10 or likely the same result if I just place 1 limit order for 1,800 shares at 50.10? Your thoughts would be appreciated.
5i Research Answer:
This size would be number of units (not board lots). Considering the liquidity of trading, we would 1,800 as one limit as the easiest and most-effective method of trade, and would not expect any material price difference overall vs multiple orders.
