Detailed Description

Price type attribute of CandleSymbol defines price that is used to build the candles.

Implementation details

This attribute is encoded in a symbol string with MarketEventSymbols.getAttributeStringByKey, changeAttributeStringByKey, and removeAttributeStringByKey methods. The key to use with these methods is available via CandlePrice::ATTRIBUTE_KEY constant. The value that this key shall be set to is equal to the corresponding CandlePrice::toString()
