#### Candles
**candle.min:** The minimum value of the current candle.
**candle.min:** The minimum price of the current candle.
**candle.max:** The maximum value of the current candle.
**candle.max:** The maximum price of the current candle.
**candle.open:** The value at which the current candle opened.
**candle.open:** The price at which the current candle opened.
**candle.close:** The latest value of the current candle.
**candle.close:** The latest price of the current candle.
**candle.direction:** Down: candle.close > candle.open | Up: candle.close < candle.open | Side: candle.close = candle.open
**candle.previous:** Refers to the previous candle. You may use _candle.previous_ to fetch any of the variables of the previous candle (i.e.: candle.previous.close). You may also use as many _.previous_ as required to fetch values of more than one period behind the current one (i.e.: candle.previous.previous.max returns the maximum value of two candles before the current one).

#### Bollinger Band
#### [Bollinger Band](https://en.wikipedia.org/wiki/Bollinger_bands)
**bollingerBand.movingAverage:** The value of the current Moving Average (20 periods).
**bollingerBand.movingAverage:** The value of the current moving average (20 periods).
**bollingerBand.standardDeviation:** The value of current the [Standard Deviation](https://en.wikipedia.org/wiki/Standard_deviation).
**bollingerBand.standardDeviation:** The value of current the [standard deviation](https://en.wikipedia.org/wiki/Standard_deviation).
**bollingerBand.deviation:** bollingerBand.standardDeviation * 2
**bollingerBand.direction:** Down: bollingerBand.previous.movingAverage > bollingerBand.movingAverage | Up: bollingerBand.previous.movingAverage < bollingerBand.movingAverage | Side: bollingerBand.previous.movingAverage = bollingerBand.movingAverage)
**bollingerBand.direction:**
* Down: bollingerBand.previous.movingAverage > bollingerBand.movingAverage
* Up: bollingerBand.previous.movingAverage < bollingerBand.movingAverage
* Side: bollingerBand.previous.movingAverage = bollingerBand.movingAverage)
**bollingerBand.previous:** Use _.previous_ like with candles (see _candle.previous_ above).
#### Percentage Bandwidth
**percentageBandwidth.value:**
**percentageBandwidth.value:** The current value of the percentage bandwidth.
**percentageBandwidth.movingAverage:**
**percentageBandwidth.movingAverage:** The current value of the percentage bandwidth moving average.
**percentageBandwidth.bandwith:**
**percentageBandwidth.bandwith:** The current bandwith.
**percentageBandwidth.direction (Down | Up | Side):**
**percentageBandwidth.direction:**
* Down: percentageBandwidth.previous.movingAverage > percentageBandwidth.movingAverage
* Up: percentageBandwidth.previous.movingAverage < percentageBandwidth.movingAverage
* Side: percentageBandwidth.previous.movingAverage = percentageBandwidth.movingAverage)
**percentageBandwidth.previous:**
**percentageBandwidth.previous:** Use _.previous_ like with candles (see _candle.previous_ above).
