You can set chart parameters when you open a chart, and modify parameters from within a chart using the Edit menu:
- Click the Edit menu within the chart window followed by Chart Parameters.
- Place a check-mark next to Adjust for dividends.
- Click Apply and OK.
When checked, prices are adjusted for dividends on the chart. The day before the dividend date, the dividend amount is subtracted from the close price.
This action will be completed automatically if you add a second ticker for comparison to the chart.
Find out more about chart parameters in the TWS Users' Guide.
