Hello All!

Each week we release a weekly updates list to show the small, regular steps we've been making to make QuantConnect better. In a given week we fix dozens of smaller bugs and often release a major feature, hopefully we can showcase these updates here.


1. Added F# and Visual Basic algorithm support in LEAN

2. Local backtesting saves charts to CSV file

3. Daily and hour bar resolution processed and now fully supported

4. Upgraded servers to use SSD disk.

5. Made LEAN an instance (removed all statics). Better support for local optimization!

Bug Fixes:

1. Thread safety of local result handler

2. Major ram usage reduction! - Changed file streaming to use streaming zips! (Kudo to @StefanoRaggi)

3. Added SetMarket support to control the data market source (for supporting Oanda, thank you again @StefanoRaggi!)

4. Rework LEAN configuration settings loading to make it more powerful

5. Converted total returns mode to be split adjusted

Big shout out to the open source contributors: @kaffeebrauer, @StefanoRaggi, @bizcad and @akoeplinger! Thank you all for making Lean better!

Happy Coding,
