Please note that if you use this in strategy that implements OnlineCalculatable ,
you should not delete any data about instrument that is expected in OnlineCalculatable.calculateValuesInRange(String, String, long, long, int, velox.api.layer1.layers.strategies.interfaces.CalculatedResultListener)
or OnlineCalculatable.createOnlineValueCalculator(String, String, long, java.util.function.Consumer, velox.api.layer1.layers.strategies.interfaces.InvalidateInterface) ,
or should handle absence of that data (in case you delete it) gracefully. |
