Re range. This is being kept there by the powers that be. IMO. Found this last night. See if you can think of a share that this fits.
VWAP Strategy
The system analyzes the trading history of a given stock, current market conditions and how venues execute orders when making decisions, Kang said. These changes have improved the performance of Dagger, which actively seeks liquidity, and the firm?s other algorithms including what he calls the ?utility? strategy that seeks to achieve the volume-weighted average price for institutional orders. VWAP is a stock?s average price over a certain period, weighted for the number of shares executed at different price levels.
?Some people think VWAP is a utility and is ubiquitous, but even VWAP can be improved by doing things right,? Kang said. Citigroup was able to "execute orders 4 percent closer on average to the market VWAP" using the new algorithm and the ?variability of performance? fell 41 percent, with fewer transactions occurring further away from the average, he said.
