going the other way until it stops going that way, and when it does you know because ittl either break the Support or stop making Higher Highs and Higher Lows.
You Draw Some Support line you draw some Resistance lines and let the trend go, it will tell u if its weak or strong by the amount of higher highs and higher lows getting larger or smaller and will tell you its consolidating when it stops making higher Highs, but until it makes Lower High assume its still trending up and consolidating if going sideways due to profit taking
