Bollinger bubbles, or Tradobubbles (from the well-known french Tradosaure), are candles that are fully outside the Bollinger bands, without any contact with them, even the wicks.

Whether a bubble is above or below the Bollinger Bands, this configuration indicates an excessive price movement. Finding bollinger bubbles can allow you to follow the correction (upwards or downwards) of this excessive movement.

Two screeners are included in this product:

• Screener “all TimeFrame”
• Screener multi TimeFrame

The “all TF” screener scans the stock market for bollinger bubbles, in the timeframe you have defined in the screener drop down menu. Results are then sorted according to the position of the detected bubble.

The Multi TF screener scans up to 9 timeframes simultaneously (regardless of the TF in the screener drop-down menu): 5‘ / 10’ / 15‘ / 30’ / 1h / 2h / 4h / Day / Weekly. The results are sorted according to timeframe and position of the bubble.

In both screeners, a general filtering, in daily TF, based on the stock price and trading volumes, allows you to fix the minimum level of liquidity required.

Many parameters and filters can be adjusted to detect the Bollingers Bubbles that meet your criteria. These settings are made without modifying the code, in the ‘variables’ menu of the screeners:
