Description

I've been exporting large data sets and downloading lots of historical data today. I have noticed that while either operation is underway, my charts do not load in MultiCharts and Portfolio Trader is unable to retrieve historical data from the database. It appears that the database does not support concurrency.

I'd think it should be possible - even if not to fill in missing data, to fill in stored data. I guess QuoteManager locks the database while it works on it.

It's really inconvenient as these operations take a great deal of time. I know I could schedule them, but I shouldn't have to. I have a "beefy" computer that can handle the load.

I am on MultiCharts .NET Build 19286.

Steps to reproduce this issue

Mode 1

  1. Initiate a Historical Data Download from QuoteManager. I specifically am using IQFeed.
  2. While that download is still in progress, attempt to backtest in Portfolio trader or load a chart in MultiCharts

Expected result: Portfolio trader backtests, charts load.
Actual result: Portfolio trader times out fetching data, charts show "backfilling" until the QuoteManager job completes.

Mode 2

  1. Initiate an ASCII data export from QuoteManager
  2. While that export is still in progress, attempt to backtest in Portfolio trader or load a chart in MultiCharts

Expected result: Portfolio trader backtests, charts load.
Actual result: Portfolio trader times out fetching data, charts show "backfilling" until the QuoteManager job completes.
