Problem with Amibroker Charts

Dear All Amibroker Experts,

In my Amibroker window i have the 3 min, 15 min, 30 min & hourly charts. In any of the charting time frames if i draw a trendline normally its getting reflected in all the timeframes . Today while i was just working on the 30 min chart some how i deleted the price indicator which is in candlestick format and then reinserted it. From then on i'm facing a problem like if i draw a line in 3min or 15 min or hourly charts its not getting reflected in the 30 min chart. I don't know what went wrong.

Can someone kindly help me out to solve the issue.

Regards,

Sonjoe Joseph

Can you check if the chart ID is consistent.
Also read below about insert or drag&drop and insert linked ways of adding indicators.

Somewhere in this context you may have broken the link.

Yes Travick the Chart ID has changed...now the problem is solved.

Thank You.
