VWAP vs. Implementation shortfall higher, volume, trade, ask

LBriscoe

I still haven't pinned down when we use which trade.

What do we use if:
- trade is large compared to daily volume?
- there is a large bid/ask spread?
- there is higher volume at the end of the day?

Unforseen

1) Broker
2) Large Bid/Ask - Broker
3) VWAP

Why not broker ?

So for part 3 (there is higher volume at the end of the day), should a broker be used or VWAP? I would have thought a broker?
