9/21 EMA Crosses Confirmed by Above-Average Volume
Summary
This script enters a long position when a 9-period EMA crosses above a 21-period EMA while volume is at least 1.5 times its 20-period average. It closes that long position when the reverse EMA crossover occurs with the same volume condition. The script also plots VWAP and Bollinger Bands, whose basis uses an EMA, but neither indicator appears in the entry or exit rules. Labels mark both EMA crosses and the volume-confirmed signals, and alerts are available for the confirmed conditions.
The document supplies implementation details but no backtest configuration, performance measurements, or evidence that the filters improve results. Its rules are long-only: bearish crosses close the long rather than opening a short. The VWAP and bands provide chart context, not additional confirmation in the actual trade logic. The crossover approach may react after a move has begun, and the document does not specify stop-loss, position sizing, or broader risk controls.
Key ideas
- A bullish EMA crossover triggers a long entry only when volume exceeds the stated average-volume threshold.
- A bearish crossover with the volume condition closes the open long position.
- VWAP and EMA-based Bollinger Bands are plotted but do not gate trades.
- The script provides labels and alerts but reports no performance evidence.
- No stop-loss or position-sizing rules are specified.
