Project Description:   
===================

The TradeFlow-Activity indicator provides a visual cue on current buying and selling activity. You define 
a share-size group to monitor and the indicator will graphically track the buying and selling over the
most recent 50 to 200 trades within that share-size group. A trade that represents buying/covering is 
plotted as a green square in the upper half of the indicator while a trade that represents selling/
shorting is plotted as a red square in the lower half of the indicator. On the right-hand side of the 
indicator the current ask and bid prices are displayed along with a percentage value that represents the 
ratio of buying to selling and vice-versa. An up or down arrow is also displayed near the bid and ask 
prices indicating the direction of the last change in price.

TradeFlow-Activity can be loaded into any intraday chart (tick or interval) at any time.

The defaults are set with the SP eMini in mind so you may need to adjust the Min/Max trades sizes to 
values that make sense for the symbol you are using.

Usage Notes:
===========

The TradeFlow-Activity indicator uses data that is available in realtime only and, as such, it provides 
no historical plot (i.e., it begins operating from the current price bar when it is loaded).
