# Rally Base Drop Signals

Rally Base Drop Signals is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®.

Rally Base Drop Signals colors price action in supply-and-demand grammar (Rally runs of bullish candles, Drop runs of bearish candles, transitional Base bars) and flags RBD and DBR reversals plus RBR and DBD continuations as they confirm. A repaint-free Color on Detection mode keeps live charts honest. Built for SND and price action traders.

**Rally Base Drop Signals** reads the chart in the native grammar of [supply and demand zones](https://www.luxalgo.com/library/concept/supply-and-demand-zones/): two or more consecutive bullish candles form a Rally, two or more bearish candles form a Drop, and the transitional candle between them is the Base, the pause where fresh zones are born. The indicator colors these candles and flags the four sequences SND traders build plans around.

## How to Trade the Rally Base Drop Signals?

- **Rally-Base-Drop (RBD)**: a bullish-to-bearish shift marking fresh supply, worth watching for a reaction when price revisits it.
- **Drop-Base-Rally (DBR)**: the mirrored shift marking fresh demand, with the same return-visit logic.
- **Rally-Base-Rally (RBR) / Drop-Base-Drop (DBD)**: continuation setups, brief consolidation before the trend resumes, valuable for scaling in with the move.
- **Base clusters**: several Base candles together suggest indecision, ranging behavior, or building orders; watch for the breakout or reversal that resolves them.

A Rally or Drop needs at least two candles, so detection lands on the second candle of the run, and neither coloring mode goes back to recolor the first one.

## Rally Base Drop Signals Settings

- **Sequences**: toggle which of RBD, DBR, RBR, and DBD are displayed.
- **Bar Color Logic**: Full Color Mode paints every Rally and Drop candle from the second candle of each run onward, the complete picture for study and post-trade review; Color on Detection paints only the candle that confirms an enabled sequence; No Color turns bar coloring off.

## Frequently Asked Questions

### Does the indicator repaint?
No. Neither mode recolors past candles: Color on Detection colors only the candle that confirms a sequence, and Full Color paints each Rally and Drop candle on its own bar. Colors and sequence labels are fixed once their bar closes; on the live bar they can change until the candle closes.

### Can I combine it with other tools?
Yes, it complements trend-following systems, order block detection, and other price action models. Let the sequences supply zone context while confirmation comes from the rest of your plan.

### How do I get it, and what if I want levels instead of signals?
It comes free with the LuxAlgo Library, and Quant, our coding agent, can test-drive it from this page. For the same candle logic distilled into pivot levels, see [Rally Base Drop SND Pivots](https://www.luxalgo.com/library/indicator/rally-base-drop-snd-pivots/). You can also copy the source code from this page and run it anywhere Pine Script® runs.
