Chart
Chart window
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.
Note! If you are using historical data, the chart will be loaded immediately. If you want to get data from a real data provider, then you must first connect to this provider.
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.
Legend menu of the Chart window
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.
Context menu of the Chart window
The context menu is accessed by pressing the right mouse button in the chart workspace.

Calculation parameters
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.
Script editor
Show connectors - the option allows you to enable / disable the drawing of connector lines in the script editor window
