On the chart this is indicated by: A trend peak under the upper Bollinger Band following the strong momentum peak above it and The slow stochastic indicator now trending down from the overbought zone. From here, a break below the 20 day moving average would confirm a trend change. This would set up for a potential test of the uptrend line and lower Bollinger Band (currently below .75)
