In this weekly bar chart of TTD, below, we can see that prices have rallied significantly the past three years. TTD has pulled back to test the rising 40-week moving average line.
The weekly OBV line shows a decline from February and the Moving Average Convergence Divergence (MACD) oscillator has crossed to the downside for a take profits sell signal.
Bottom-line strategy: Prices can go down too fast and they can be considered oversold but that does not necessarily make them a buy, like TTD for example. Prices may test and hold the rising 200-day moving average line but our indicators are not (yet) indicating that will happen. Stand aside for now.
