If your indicator, such as MQ Trend, appears on a subgraph or subpanel, and you want it to appear on the same panel as the price chart, see if the following instructions will work for you.
Open your studies (F6), select the study that you've added to the chart, and select the Settings button to open Study Settings. Then in Study Settings, locate the Chart Region pulldown at the left of the dialog box, and select the chart region that the main price graph is on, which is typically region 1. You can see region 1 being selected in the image, below. This will move the indicator to the main price chart.
To make region 1 the default for this indicator, click on the Set Defaults button (at the lower right of the Study Settings dialog, also shown in the image, below), which will set all of the current indicator's settings as the default the next time it's added to a chart.
