MarketAnalyzer Column returning whole numbers

[swcooke]

I've created a MarketAnalyzer Column that calculates the Current Price - Previous close. It Prints the correct values to the console however, the column shows the values as something entirely different. Here is code and I've also attached the script if you want to test:

        double prevClose = 0;
        double priceChange = 0;
        protected override void OnMarketData(Data.MarketDataEventArgs marketDataUpdate)
        {
            if (marketDataUpdate.IsReset){
                CurrentValue = double.MinValue;
                return;
            }

            if (marketDataUpdate.MarketDataType == Data.MarketDataType.Last){
                if(marketDataUpdate.Price == null)return;
                //if prevClose has not been set yet
                if(prevClose == 0)return;

                priceChange = Math.Round(marketDataUpdate.Price - prevClose,2);
                //This prints the value as expected
                Print(priceChange);
                //However the value in the column does not display correctly
                CurrentValue = priceChange;
                return;
            }
            if (marketDataUpdate.MarketDataType == Data.MarketDataType.LastClose){
                if(marketDataUpdate.Price != null){
                     prevClose = marketDataUpdate.Price;
                }
            }            

        }

Here is a screenshot of the values shown in my window vs. what Prints out:

Hello swcooke, thanks for your post.

It looks like the DataType property is an int instead of a double. Add this to State.SetDefaults:

DataType = typeof(double);

Please let me know if I can assist any further.

Hi Chris,

Sorry for the late reply on this. I have followed your instructions but it still does not output the correct value in the MarketAnalyzer window even though I have made the suggested change. Attached is my simply column. Can you run this and let me know what I am doing wrong? Here it is: npImpact.zip

Hello swcooke,

I was also able to reproduce.

I'm seeing the text is being formatted in Format() override.

You are using 'Core.Globals.FormatQuantity((long) value, false);' to return an int.


Try printing on line 68:
Print(string.Format("priceChange: {0}, FormatQuantity(): {1}", priceChange, Core.Globals.FormatQuantity((long) priceChange, false)));

Thanks! That solved the issue.
