Main chart.

 
How we can insert indicators such as williams s/r, rsi, cci, in main chart window??
 
Hua,

Left hand column has a Navigator section. Indicators are located there. Locate the ones you're after and drag them from the Navigator onto the chart. You can adjust various settings once dropped onto the chart.

there indicators have different scale. in the chart used price scale and this scale applied to the all chart indicators. therefore insertion of these indicators is useless - they will be invisible in the price scale
