What is it

This is a static and streaming provider for Wealth-Lab Developer that downloads free intraday and daily historical price data provided by Russian company "MFD". It covers all Russian exchanges and a number of world indices, futures and currency pairs (Forex). Historical data downloads are multithreaded and fast.

Setting up

It's required for the MFD provider provider to work that you download classification groups. When creating the very first DataSet, you'll be prompted to do it:

Classification not found

Classification groups

Currently, MFD offers historical data broken in 25 supported groups ranging from Russian markets to world indices. Classification will be downloaded from MFD's site and stored in your AppData folder. Once classificiation is saved locally you can create new DataSets by selecting symbols from the various groups:

At any time you can refresh the classification groups by loading the "Create dataset" dialog box and clicking "Refresh". This step is helpful when the data vendor adds new symbols or removes dead entries.

You can select all instruments from a market group by double clicking on its title. To remove a range of instruments, click on the first one in the right pane and press Shift-Home (from here to the beginning) or Shift-End (from here to the end), or click with Shift or Ctrl pressed (multiple selection) etc.

Streaming data

Provider supports free Streaming intraday and daily data. To enable, open the Wealth-Lab's Preferences dialog > "Streaming Data" and tick the "MFD Streaming Provider".

To conserve bandwidth and reduce server load, partial bars are updated once every 10 seconds for snapshot quotes.

Weekend bars

MFD data may include data on weekends. Sometimes this is correct and sometimes totally wrong. For example, it's correct for Russian stocks and bonds because from time to time these markets may trade on Saturdays (the so called "Black Saturdays"). And cryptocurrencies just trade every day. For mostly all the rest, the weekend bars are plain wrong and are probably caused by timezone offset (by the time a U.S. exchange closes for the weekend it's already Satruday in Moscow).

You can control how the provider handles this in the "Create New DataSet" on a per DataSet basis. "Keep weekend bars" is disabled by default, effectively merging the fake Saturday trading with the preceding Friday bar and then deleting the weekend bar. Check this box for all Russian markets (RTS, FORTS, MOEX, SPFB) and cryptocurrencies to preserve the bars as is. Keep it disabled for everything else like ADRs, Forex currencies, international indices, global futures and commodities.

Partial bar

Although the partial bar isn't included in MFD's Daily data, some users prefer seeing today's incomplete bar. To enable it on a per DataSet basis, check that option in "Create New DataSet". It will add today's "ghost bar" to the data in Daily DataSets (only).

Note: there will be no partial bar during on demand data update, Strategy Monitor operation or "Reload chart history".
