Line modes

The chart plots one of two families of lines. The console, the ladder and every alert follow the line the chart is set to: the core line in Flow mode, the Buy and Sell lines in Buy / Sell mode.

Mode Lines drawn Band
Flow (default) Total Flow, Passive Flow, Aggressive Flow, Placement Flow (hidden by default) Flow Resistance / Flow Support, sized from the core line
Buy / Sell Buy Line and Sell Line (the two passive sides, or the two placement sides), and the Delta Line (Buy minus Sell) Buy/Sell Resistance / Buy/Sell Support, one shared band

Resistance and Support lines are always drawn.

Why modes rather than toggles: the two families live on very different scales. The buy and sell lines are running totals of one side of the book, which on a busy instrument can reach tens of thousands of contracts, while Total Flow is their difference, often a few thousand. Plotting them together squashed the flow lines flat. One family per panel keeps every line readable.

The Delta line

Earlier versions had a separate Delta line: buy-side flow minus sell-side flow. In Flow mode it is the Passive Flow line. The Buy / Sell mode has it too, as the Delta Line, so a 2.x layout with Buy, Sell and Delta can be set up again. See buy & sell lines.

Switching modes

  • Bookmap: Settings → Configure add-ons → Pulling & Stacking Indicator → Parameters → Line Mode*, then Apply core settings changes and restart indicators. The Line Colors section lists only the lines of the saved mode.

Switching modes does not restart the warm-up of the flow lines: the flow engine keeps its history, only the lines are re-registered. The Buy / Sell band is kept only while a chart is in Buy / Sell mode, so it warms up over one primary window (five minutes by default) when you switch to that mode.

Hiding an individual line

  • Bookmap: the gear at the top of the widget pane lists the lines of the current mode; each has one button for the line and one for its widget.

Risk disclosure. Futures and forex trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing one's financial security or lifestyle. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

The Pulling & Stacking Indicator is an analytical tool. It does not provide investment advice or trade recommendations, and nothing it displays is a signal to buy or sell.

Hypothetical performance disclosure. Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. For example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
