Chart Analysis is used for risk management, it can show a trend over many days. It should be the number one thing you use, news like we got today didn’t do anything, it followed the downtrend that it’s in.
chart= trend : down or up. and reversals. both ways. it is more reliable with solid stocks. calm stocks.and over multi weeks multi months , year periods. and for daytrading.( intraday tops and bottoms) problem is to be disciplined and follow the chart and not think it will go down or up.. ( aka hope)
