Decimal
class has been replaced by newNum
interface. Enables usingDouble
,BigDecimal
and custom data types for calculations.- Big changes in
TimeSeries
andBaseTimeSeries
. Multiple newaddBar(..)
functions inTimeSeries
allow to add data directly to the series
- TradingBotOnMovingTimeSeries: fixed calculations and ArithmeticException Overflow

Num
. - AbstractIndicator: new
AbstractIndicator#numOf(Number n)
function as counterpart of droppedDecimal.valueOf(double|int|..)
- TimeSeries | Bar: preferred way to add bar data to a
TimeSeries
is directly to the series via newTimeSeries#addBar(time,open,high,..)
functions. It ensures to use the correctNum
implementation of the series - XlsTestsUtils: now processes xls with one or more days between data rows (daily, weekly, monthly, etc). Also handle xls #DIV/0! calculated cells (imported as NaN.NaN)
- CachedIndicator: Last bar is not cached to support real time indicators
- **TimeSeries | Bar **: added new
#addPrice(price)
function that adds price to (last) bar. - Parameter timeFrame renamed to barCount.

Number
parameters - AroonUpIndicator: redundant TimeSeries call was removed from constructor

calls. - ChopIndicator: transparent fixes

Math.sqrt(double)
toNum.sqrt()
, other small improvements - RandomWalk[High|Low]Indicator: renamed to
RWI[High|Low]Indicator
- BaseTimeSeries.SeriesBuilder: simplifies creation of BaseTimeSeries.
- Num: Extracted interface of dropped
Decimal
class - DoubleNum:
Num
implementation to support calculations based ondouble
primitive - BigDecimalNum: Default
Num
implementation ofBaseTimeSeries

Num
interface - TimeSeries#addBar(Bar bar): deprecated. Use
TimeSeries#addBar(Time, open, high, low, ...)

BaseTimeSeries(TimeSeries defaultSeries, int seriesBeginIndex, int seriesEndIndex)
removed. UseTimeSeries.getSubseries(int i, int i)
instead - FisherIndicator: commented constructor removed.

BaseTimeSeries(TimeSeries defaultSeries, int seriesBeginIndex, int seriesEndIndex)
removed. UseTimeSeries.getSubseries(int i, int i)

NaN
the criterion uses the price of theOrder
and not just the close price of underlyingTimeSeries

sell/buyAt(..)
functions need a price and amount parameter to satisfy correct be behaviour of criterions (entry/exit prices can differ from corresponding close prices inOrder
) - JustOnceRule: now it is possible to add another rule so that this rule is satisfied if the inner rule is satisfied for the first time
