 | isConnectionOpened        | Sets the connection status. If set, upon reconnection smartcharts will either patch missing tick data or refresh the chart, depending on granularity; if not set, it is assumed that connection is always opened. Defaults to `undefined`.                                                                                                                       |
 | onMessage                 | SmartCharts will send notifications via this callback, should it be provided. Each notification will have the following structure: `{ text, type, category }`.                                                                                                                                                                                                   |
 | isAnimationEnabled        | Determine whether chart animation is enabled or disabled. It may needs to be disabled for better performance. Defaults to `true`.                                                                                                                                                                                                                                |
-| isVerticalScrollEnabled   | Determine whether verticall scroll on the chart outside Y-axis is disabled. It may need to be disabled for mobile app version to scroll the page up or down instead of the chart. Defaults to `true`.                                                                                                                                                                                                                                |
+| isVerticalScrollEnabled   | Determine whether verticall scroll on the chart outside Y-axis is disabled while it is forced on the nearest scrollable parent instead. It may need to be disabled for mobile app version to scroll the page up or down instead of the chart. In this case, when scroll delta exceeds 10px, the page will be force-scrolled fully in the respective direction. Defaults to `true`.                                                                                                                                                                                                                                |

 | scrollToEpoch             | Scrolls the chart to the leftmost side and sets the last spot/bar as the first visible spot/bar in the chart. Also, it disables scrolling until the chart reaches the 3/4 of the width of the main pane of the chart.
