I'm a dividend investor, I use charts with the yield graphed under the stock price, I look historical h/l to find good exit/entry points. One problem with many data vendors is when the stock splits the dividend is not handled correctly - your data seems to correct for that...this is really nice!!!!!! You should advertise that...I'm uploading a Thinkorswim chart to show you the problem....the Koyfin charts seem to not have this problem - at least not with MKC....well done man!!!!!
