A chart is one of the main ways to visually represent numerical data and conduct technical analysis. A feature of the TSLab program is a powerful and flexible system for setting up the display of charts. You can use the preset chart display settings or customize the chart display to suit your needs. The "Chart" window can be opened from the Main menu | View | Chart or from the context menu of the "Quotes" window opened above the instrument, you are interested in.
Open a simple chart.
In the window that opens, right-click on the chart workspace. Select Properties from the context menu.
In the Properties: Chart window, select the Sources tab. In the Instrument line, select the paper you are interested in
Open the Chart tab. Disable the option Use initial date. This option allows you to limit the amount of trading data downloaded from the server. It is enabled by default. Confirm the selected settings by clicking the OK button.
The chart has its own editor to display indicators using it. In the chart editor, some blocks that cannot be used in the chart are disabled, for example, entering a position and exiting a position.
When the "flag" is set, the line is displayed on the chart, when the flag is removed, it is not displayed. The legend menu has the function of binding to its panel. Hover your mouse over the legend, click:
When changing the size of the chart panels, the legend remains in the same place. The Legend menu can be moved around the chart. Move the mouse cursor over the Legend, hold down the left mouse button, move the cursor to the desired location on the chart, release the mouse button.
The context menu is accessed by pressing the right mouse button in the chart workspace.

Properties of the Chart window can be opened using the context menu or using the Window properties button (Main menu - Edit). The properties are located on the Graph tab.
For each chart, at least one data source must be defined, this is the security whose indicators will be displayed on the chart.
Depending on the chart template, if it contains several data sources, the chart may contain information on several securities.
A security is selected in the Select Instrument window. In this window, you can select a data provider (a broker providing information), a type of securities, and also use a securities filter.
Data provider
Selecting a data provider.
Type
Selection of tool type.
Market
Market selection.
Instrument list
List of securities available for selection. You can search for the required paper in the Search bar. Next to the search bar there is a drop-down menu that allows you to select an Exact or Fuzzy match of the input query to the name of the paper you are looking for.
Do not show strikes
Exclude strikes from the list of instruments.
Do not show expired
Excludes expired instruments from the list.
Expiration
Choice of expiration type:
after;

For convenience, when working with futures, it is possible to display different securities for different time periods on the chart. Thus, the program gives you the opportunity to combine the data of various financial instruments.
The selected instruments are placed in the "Source" field of the Properties: Chart window. Click on + Add Instrument to open the tool for adding start and end dates to be used for plotting. The newest tool should be selected as the first tool.
An installed tool can be removed by clicking on the "X" (Clear instrument) button.
Properties of the Chart window can be opened using the context menu or using the Window properties button (Main menu - Edit).
Recalculation Interval
Management of agent recalculation mode and creation of commands in real trading mode:
Interval;
Interval + first trade;
Interval (for events)
Trade;
Buy / Sell;
Buy / Sell (without volume).
Real time update
Enables real-time update and recalculation in lab mode. This mode is used to simulate the agent's work with real data.
Recalculation in Every Source
If the strategy uses several data sources, when this option is enabled, recalculation will occur when a new candle is opened for each source. This option does not affect the "Deal" and buy/sell modes..
Interval Period
Chart update interval:
Days (the time interval between adjacent candles is one day);
Minutes (the time interval between adjacent candles is one minute);
Seconds (the time interval between adjacent candles is one second);
Ticks (the chart update period is fluctuations in the price of a security);
Volume;
Price step.
Attention! Seconds and Tiki are built on the basis of information about transactions.
Interval
Chart update interval.
Date from
Start date of the chart.
Use initial date
Enables the use of a start date. If not enabled, the maximum amount of data available is used, determined by the source.
Date to
Chart end date.
Use end date
Enables the use of an end date. If not enabled, the maximum amount of data available, determined by the source, is used.
Reload date
The date from which you want to reload the chart data.
Use reload date
Activates the application of the selected date from which to reload the chart data.
Maximum days
Allows you to limit the amount of requested historical data (from "Date to"). The value "0" - the number without limitation.
Session beginning
Sets the time intervals for the session.
Session end
Sets the time intervals for the session.
Maximum bars
The maximum number of bars used for the calculation. This setting allows you to limit the number of bars when the agent works in real time to avoid redundant calculations.
Decompression method. Method of decompression of compressed data in the calculation/optimization mode on historical data.
This parameter determines the time shift of the data calculated for the compressed time intervals during decompression to the original (base) time interval. Example: The basic calculation interval is 1 minute. To calculate the indicators used compression in the interval of 1 hour. 12 hour bar = 12.00 - 12.59 minutes.
When decompressing indicators:
1st method: the value 12.00 takes effect (becomes available for calculations within the script) from the minute bar 12.59.
2nd method: the value 12.00 takes effect (becomes available for calculations within the script) from the minute bar 12.00.
3rd method: the value of 12.00 takes effect (becomes available for calculations within the script) from the minute bar at 13.00.
Attention!
Method 1 is the most optimal for optimizing trading strategies.
The 2nd method is not recommended for testing strategies due to the possible "looking into the future", because the value of the compressed indicator is available until the end of the hour! The 2nd method is applicable exclusively for visual and graphical analysis.
The 3rd method has a small delay equal to one base interval and can be used to test strategies based on short (second) intervals to simulate possible execution delays, such as slow communication channels, etc.
Show connectors - the option allows you to enable / disable the drawing of connector lines in the script editor window
Bar size
The parameter sets the width of the bar in pixels on the chart.
Bars indent
Offset of the right edge of the chart from the axis, in pixels.

Time scale
Selecting the type of timeframe:
simple timescale. Each cell of the grid is filled with an equal number of candles, the timeline displays the time corresponding to the last candle of the cell;
adaptive timescale. The grid cell size adjusts to the actual number of candles in the selected time unit.
Using the adaptive timescale is possible if Days, Minutes or Seconds are used as the Interval period. In case of using Volume or Price Step, a simple timescale is applied.
