getData (SDK Trading)

getData is a Fintechee API to get the data of the specific chart or indicator by the handle(a kind of selector) of the chart or indicator.

You can call the getChartHandle and the getIndicatorHandle APIs to get the handle of the specific chart or indicator. The handle would be used to get the data in the onTick callback function. So you need to transfer it to the onTick function by setting it as a property of window object.

You need to specify the name to get the corresponding data because the handle may stand for several lines of a chart or indicator. For example, MACD has two lines as the outputted data(main and signal), so you need to make the API know the data of which line to get.

The data returned by the getData API are organized as an array. The index zero of the array(n-length) refers to the oldest data, the latest index(n - 1) refers to the latest data.
