When you take a trade, you must make sure that the Average directional index is moving upwards and is above 25. If the trend moves upwards then it resembles that the trend is becoming strong.

When we studied hundreds of our publishers, Google (AdX) ranked as the top demand partner that contributes to more than 50% of the total programmatic revenue. We must buy at the next candle after the positive crossover and place the stop loss at low of the previous candle. The next time you think a trend is changing and you need to decide whether to stick to this “friend” or cut ties, consider trying the ADX to confirm the trend’s strength.

For example, sometimes a high ADX reading could be a sign that a market has been depleted of its current trend strength, and soon is about to turn around. In other words, some trend-following or breakout strategies may have a lot in common with mean reversion trading strategies when coupled with high ADX readings. The general interpretation is that ADX values above 25 signal a strong trend, while readings below 15 suggest a calm market that’s not trending at the moment. Then, depending on the ADX level, we may decide to employ mean reversion or trend following strategies. For example, we might want to go long on a new breakout only if ADX is showing high readings, which signals that the trend is strong and healthy.

ADX Calculation

Notice that there was no sell signal between the March and July buy signals. This is because ADX was not above 20 when -DI crossed above +DI in late April.

When ADX is below 25 for more than 30 bars, price enters range conditions, and price patterns are often easier to identify.

A couple of weeks later, the ADX quickly drops below 25—which marks the end of the stock’s upward trend. Soon after that, the -DMI line crosses above the +DMI line and the ADX shoots up above 25 again, which means that the stock is about to go on a sharp downward trend.
