toBool

Convert a number to a boolean.

Signature

toBool(v: number) => boolean

Parameters

NameTypeDescription
vnumberthe value to convert.

Returns

boolean


tr

True Range

Signature

tr(n_handleNaN: number, ctx: IContext) => number

Parameters

NameTypeDescription
n_handleNaNnumberHow NaN values are handled. If truthy, and previous bar's close is NaN then tr would be calculated as current bar high-low. Otherwise tr would return NaN in such cases. Also note, that atr uses tr(true).
ctxIContextPineJS execution context.

Returns

True range. It is max(high - low, abs(high - close[1]), abs(low - close[1]))

number

NameTypeDescription
ctxIContextPineJS execution context.

Returns

Symbol unit ID.

string


updatetime

Signature

updatetime(context: IContext) => number

Parameters

NameTypeDescription

Returns

symbol update time

number


variance

Variance is the expectation of the squared deviation of a series from its mean sma, and it informally measures how far a set of numbers are spread out from their mean. Note: This is a biased estimation of sample variance.

Signature

variance(source: IPineSeries, length: number, context: IContext) => number

Parameters

NameTypeDescription
sourceIPineSeriesSeries of values to process.
lengthnumberNumber of bars (length).
contextIContextPineJS execution context.

Returns

Variance of source for length bars back.

number


volume

Current bar volume

Signature

volume(context: IContext) => number

Parameters

NameTypeDescription
contextIContextPineJS execution context.

Returns

Current bar volume

number


vwma

The vwma function returns volume-weighted moving average of source for length bars back. It is the same as: sma(x * volume, y) / sma(volume, y)

Signature

vwma(source: IPineSeries, length: number, context: IContext) => number

Parameters

NameTypeDescription
sourceIPineSeriesSeries of values to process.
lengthnumberNumber of bars (length).
contextIContextPineJS execution context.

Returns

Volume-weighted moving average of source for length bars back.

number


weekofyear

Week number of current bar time in exchange timezone.

Signature

weekofyear(context: IContext, time?: number) => number

Parameters

NameTypeDescription
contextIContextPineJS execution context.
time?numberoptional time. Current bar time will be used by default.

Returns

Week number of current bar in exchange timezone.

number


wma

The wma function returns weighted moving average of source for length bars back. In wma weighting factors decrease in arithmetical progression.

Signature

wma(source: IPineSeries, length: number, context: IContext) => number

Parameters

NameTypeDescription
sourceIPineSeriesSeries of values to process.
lengthnumberNumber of bars (length).
contextIContextPineJS execution context.

Returns

Weighted moving average of series for length bars back.

number


year

Year of current bar time in exchange timezone.

Signature

year(context: IContext, time?: number) => number

Parameters

NameTypeDescription
contextIContextPineJS execution context.
time?numberoptional time. Current bar time will be used by default.

Returns

Current bar year in exchange timezone.
