Some times I like to break up a sell into smaller parcels.
I buy some stocks where if I try to sell 300k units I stand out and it looks like an Algo trade(a dummy sell to distort market depth). Some times it can give the impression it's a block. I also find that when an Algo reaches my trade it plays with it. Takes nibbles and then executes from others, both when I buy and sell. CommSec gives you some quibble about it being a CS client being matched with my order, any one know much about this 'truth'??? I find this doesn't happen as often with smaller orders...hmmmm!
I once had a large order several lines below the current bid. It executed part of it. I then decided I wasn't hanging around so canceled the remainder to go to another stock. I had to end up selling at a loss because it was a T+1 and I wasn't prepared to leave an over night position. Yes, the risk you take BUT I don't believe any order should execute unless you are NEXT in line. It felt like a conspiracy, execute some and he'll move up to execute the rest, like wise when selling. Always scamming to make you pay more or sell for less.
I now make sure I can hold with no consequence, eventually they break down and need oiling. Some days on a slow stock you can bet on which minute it will execute next.
