Question about it...

Posted by: Utech on Mar 26, 18:13 in response to Patient Player's post Yes, ca..1998

 am reading through it and the program that determines the price movement is:

PM=(NMS/LMV)*SIV

PM: Price Movement

NMS: the net movement in sweep - difference in buy and sell orders of a stock.

A sweep increment variable (SIV) is defined as the increase or decrease in price caused by an incremental imbalance in the number of buy orders and sell orders. A lot movement variable (LMV) represents the incremental lot size that will result in a price increase or decrease of one SIV.

 I am trying to figure out if these are calculated somehow, or if they are variables are set by an administrator, and then saved in the system as a constant. Also, if each stock has its own SIV and LMV, or if they all share a global SIV and LMV.
