I cannot read normally charts, however there are free instruments like swingtradebot for Australia or London Stock Exchange or Canada that I found helpful. There are shares that stay quite long with high or low rates indicating sort of like or dislike. Sau is rated for some time worst Rating F , Blue Merchant is rated B (second best rating) also for some time. Could reflect thrust in management and/or management costs..
