The Price Chart in DeepCharts — whether shown as a candlestick or a line chart — is an indicator that helps you visualize the historical transactions of buyers and sellers based on the order book.
You can fully customize how this visualization appears using the options provided in the chart settings.

When you click on the Candlestick button on the top bar, a dropdown menu appears, as shown below:

By default, the chart is set to Candlestick view, but you can change it to:

1.1 Line Chart

Displays price movement as a continuous line connecting closing prices of each candle.

1.2 OHLC (Open High Low Close)

1.3 Equi-Volume Bars

When this option is enabled, you’ll notice that candle widths vary — some are thicker and others thinner.
The width of each candle represents the traded volume during that period.

• Thicker candles = higher trading volume.

• Thinner candles = lower trading volume.

This allows you to quickly identify periods of heavy or light trading activity.

1.4 Delta-Volume Bars

When enabled, the color intensity of each candle changes based on delta values (the difference between aggressive buyers and sellers).

• Darker red = more aggressive sellers (negative delta).

• Darker green = more aggressive buyers (positive delta).

The stronger the color intensity, the greater the imbalance between buyers and sellers.
This feature helps traders spot absorptions and exhaustions in the market more easily.

1.5 ETH Session

When enabled, the chart displays prices from the Electronic Trading Hours (ETH).
When disabled, it only shows data from the Regular Trading Hours (RTH) for that instrument.

1.6 Countdown Timer

If enabled, a countdown appears at the bottom-right corner of your chart, showing how much time is left before the current candle closes — helping you anticipate upcoming candle formations.

2. Types of Time Charts

In DeepCharts, there are several types of chart structures that represent market activity differently. Each chart type serves a specific analytical purpose, depending on whether you want to focus on time, price movement, volume, delta.

2.1 Time-Based Charts

These are the most common chart types, where each bar or candle represents a fixed period of time.
You can select from:

• Seconds

• Minutes

• Daily

• Weekly

• Monthly

Each candle closes when the selected time frame ends, regardless of how much price or volume movement occurred.

2.2 Range Bars

Range bars are not time-dependent — they are based purely on price movement.

For example, if you set a range of 8 ticks, each bar will represent a price movement of up to 8 ticks between its high and low.

If price moves beyond that range (for example, to the 9th tick), a new bar will automatically form.

These bars can also be smaller than 8 ticks — for instance, if a bar moves 5 ticks up but the spread quickly increases by 6 ticks (exceeding the range), the bar will close early, and a new one will open.

This type of chart helps traders identify small price gaps and micro-imbalances in the order book that are harder to spot on standard time-based charts.

2.3 VolBar (Volume Range Bar)

A VolBar is a variation of the range bar, but it includes a reversal parameter.
It uses two key inputs:

• Target: the number of ticks required for a bar to complete.

• Reversal: the number of ticks the price must move in the opposite direction before the bar closes

Example:

If you set Target = 8 and Reversal = 4:

• The bar won’t close when price moves 8 ticks up (as a normal range bar would).

• It will only close once price retraces 4 ticks in the opposite direction.

This structure helps traders visualize trend continuation and pullbacks more clearly.

2.4 Volume Bars

In Volume Bars, each bar closes once a specific volume threshold is reached — not based on time or price.

For example, if you set the volume to 1,000, each bar will represent 1,000 contracts traded in total.
This gives traders a better sense of trading activity intensity instead of just elapsed time.

2.5 Trades Bars

Unlike Volume Bars (which are based on the total contracts traded), Trade Bars are based on the number of transactions.

For example, if you set the parameter to 10 trades, then each bar represents 10 completed trades, regardless of how large or small those trades were.
This helps analyze transaction frequency and market participation rate.

2.6 Delta Bars

Delta Bars are similar to Volume Bars, but instead of total traded volume, each bar forms based on delta — the difference between aggressive buy and sell orders.

These bars are useful for understanding buying and selling pressure in real-time and identifying when one side of the market starts to dominate.
