## Big Delta

Retail traders cannot cause these repeatedly high amounts of sudden order flow.

## Delta Shift

A "Delta Shift" occurs when a new and significant Delta Flag appears immediately in the opposite direction of the previous Delta Flag.

This shift may indicate a potential market reversal or strengthen the overall trading strategy, suggesting that it's time to assess the next potential trade setup.

## FlowMaster™ Delta Flagging Settings

Default AlgoBox™ settings are shown.</p></figcaption></figure>

### 1. Audio

The audio alerts you once Delta Up , Delta Down, or a Double Delta has been detected. You can customize these alerts by changing the audio to a preferred voice or sound, or turn them off entirely.

<mark style="color:yellow;">Standard Sound On/Off:</mark> Toggle ON or OFF to receive sound alerts.

<mark style="color:yellow;">Delta Down Building:</mark> You can customize and add your own sound for the Delta Down Building alert.&#x20;

<mark style="color:yellow;">Delta Up Building:</mark> You can customize and add your own sound for the Delta Up Building alert.

<mark style="color:yellow;">Double Delta Sound On/Off:</mark> Toggle ON or OFF to receive sound alerts when a double delta is detected.

<mark style="color:yellow;">Double Delta Sell Sound:</mark> You can customize and add your own sound for the Delta Sell alert.

<mark style="color:yellow;">Double Delta Buy Sound:</mark> You can customize and add your own sound for the Delta Buy alert.

<mark style="color:yellow;">AlgoVoice Standard:</mark> Toggle ON or OFF to receive sound alerts for Delta Up/Down in AlgoVoice.

<mark style="color:yellow;">AlgoVoice Double:</mark> Toggle ON or OFF to receive sound alerts for Double Delta in AlgoVoice.

<mark style="color:yellow;">Voice Rate:</mark> You can customize the speed of the AlgoVoice alerts to your preference.

All custom sounds must be in .wav file format only.

### 2. Calculations

Allows you to control how frequently the FlowMaster™ Delta Flagging indicator recalculates. The Calculation sets the frequency of these calculation cycles. Customization allows for greater control over data update rates.

<mark style="color:yellow;">Calc Override:</mark> Default setting is unchecked. Check this setting to customize and utilize Calc Interval.

<mark style="color:yellow;">Calc Interval:</mark> Set your custom desired calculation interval. The smaller the number, the more frequently the indicator will recalculate, which increases processing load on your system's CPU. The default setting of 1000 is in milliseconds, which is equal to 1 second. If you wanted the FlowMaster™ Delta Flagging to calculate every half second (twice as fast as default 1000ms), then you would enter 500 in this field.

<mark style="color:yellow;">Alert Threshold:</mark> Allows you to customize the size of Delta Flags that meet the threshold for a forced calculation, whether its small, medium or large (default).

### 3. Custom Settings

<mark style="color:yellow;">Draw Horizontals:</mark> Enables you to toggle the visibility of horizontal lines on the chart.

<mark style="color:yellow;">Global Horizontals:</mark> Applies horizontal lines across all charts in your workspace for consistency.

<mark style="color:yellow;">Number of Horizontals:</mark> Sets the maximum number of horizontal lines to be displayed on the chart.

[Click here to learn more about drawing global objects across all charts.](https://docs.algoboxpro.com/tips/indicators#video-tutorial-how-to-draw-global-objects)

### 4. Visual Settings

Enables customization of colors and line styles (dashed or solid) for various settings, including font type/size, Delta Up, Delta Down, and toggling Double Delta visibility on the chart when detected.

<mark style="color:yellow;">Show Double Delta Verticals:</mark> Toggle ON or OFF to show the highlighted Ready DD vertical bars.

<mark style="color:yellow;">Show Delta Shift Verticals:</mark> Toggle ON or OFF to show the yellow Delta Shift vertical bars.

### 5. Data Series&#x20;

Displays the current chart instrument, contract date and configurations applied.

<mark style="color:yellow;">Input Series:</mark> This setting determines which chart the indicator is displayed on, linking the indicator to the selected chart data.

### 6. Setup

Allows you to add a label, set the maximum bars to look back, and configure calculations based On Price Change, On Bar Close, or On Each Tick.

<mark style="color:yellow;">On Price Change:</mark> Updates the indicator only when there is a change in the instrument's price.

<mark style="color:yellow;">On Bar Close:</mark> Updates whenever a new bar closes, recalculating based on the finalized bar data to reflect the latest market conditions and changes in trends. Be mindful of whether you are using AlgoBars or range bars. This is the default setting for this indicator.

<mark style="color:yellow;">On Each Tick:</mark> Updates with every price change or tick in the market, providing real-time adjustments and reflecting the most current data. This setting increases CPU processing load.

### 7. Visual

Allows you to customize button colors, adjust the button placement, and modify the font type and size to suit your preferences. The Visual Settings shown are default settings which usually do not need to be changed unless specified in release notes or instructional video, live stream or on Discord etc. Auto scale is recommended to be unchecked.

<mark style="color:yellow;">Auto Scale:</mark> Automatically adjusts the indicator’s scale to fit within the chart’s price axis, ensuring it’s properly visible without manual adjustments.

<mark style="color:yellow;">Displacement:</mark> Shifts the indicator's plot forward or backward on the time axis. This setting is useful for aligning the indicator with price bars or other chart elements, especially in cases where you want to visualize future or past data relative to the current price.

<mark style="color:yellow;">Display in Data Box:</mark> Determines whether the values are shown in the Data Box, which is an on-screen display that provides detailed information about the current values when you hover over or click on the chart.

<mark style="color:yellow;">Panel:</mark> Specifies which panel or sub-panel the indicator is displayed in on the chart. Indicators can be placed in separate panels above or below the main price chart, allowing for organized and uncluttered visualization of multiple indicators.

<mark style="color:yellow;">Price Markers:</mark> Controls the display of markers or symbols on the price axis associated with the indicator's values. This setting helps highlight specific price levels or events directly on the price chart for better visibility and analysis.

<mark style="color:yellow;">Scale Justification:</mark> Determines where the indicator is positioned on the price scale, such as to the right or left side of the chart.

<mark style="color:yellow;">Visible:</mark> Toggles the overall visibility of the indicator, allowing you to hide or show it on the chart as needed.

{% hint style="warning" %} <mark style="color:yellow;">All settings displayed in the settings image are the current default configurations provided by NinjaTrader and/or the AlgoBox™ Pro software, and may change at any time in future software updates without notice.</mark>
