I'm trying to better understand the difference between the VWAP and DMA Strategies in Bloomberg through the EMSX function.
As far as I understand is putting orders in Direct market access(DMA) a way to throw them in the market to be filled just like that. Best done when the total volume allows it.
The VWAP or Volume weighted averaged price is calculated by the following:
$VWAP= (∑Volume *∑Price )/ ∑Volume$
This is comparable to the moving average strategy.When the VWAP is under current price it becomes interesting to buy. The other way around when it is above current price it becomes interesting to sell.
What I'm trying to understand is :if for example a trader has Equity he wants to sell and uses the VWAP strategy trough a child order it will only sell the stocks when the VWAP is under current market Price. This until the VWAP rises and goes above the market price then it will stop filling the orders.
Is my understanding of these concepts correct and are there possible alternatives to the VWAP strategy in Bloomberg?
Thanks in advance!
