Settings-of-Use

Clicking on the indicator settings icon will open its configuration window, within which you will be able to make several choices regarding the functionality of the indicator itself.

• Parameters

• Database

Defines which database to use to calculate the indicator, specifically you can choose from:

1. Volumes

Indicate the quantities of contracts/shares traded,

2. Trades

Indicate the number of trades, 

In other words, Trades indicate how often a financial instrument is traded, while Volumes indicate how much of the financial instrument is traded.

For example, an increase in the number of Trades without a corresponding increase in Volumes indicates that there is frequent activity but on small amounts. Conversely, an increase in Volumes without a corresponding increase in the number of Trades indicates that few traders are moving large quantities.

• Filter-min

Allows you to apply a minimum filter to the indicator; 

• Filter max

Lets you apply a maximum filter to the indicator, if the value 0 is left the indicator will not append any maximum filter;

• Restore-to-start-session

If enabled, it allows you to restart with the cumulative delta calculation every session start.

• Series

In this section you can define the colors of the indicator; the style of the series, choosing between Bars and Line; the style of the line, choosing between Solid and Hatch; the thickness of the line.

You can also show the name and value of the indicator as well as enter a custom name.

By default, the indicator will show green bars if the cumulative delta is positive, indicating a prevalence of buy market over sell market, red bars if cumulative delta is negative, indicating a prevalence of sell market compared to buy market.

In the image below, two indicators Comulative Delta have been added in the same Horizontal Area Chart.

The former uses a Volumes and series style at Bars, the latter uses a Trades and series style at Line.
