Over two (fun!) years the QuantConnect team have assisted me in

(1) My programming...which at the beginning was all but non-existent. With this, the customer support, community help and other resources e.g. GitHub provided me with the required information to develop my algos.

(2) Connectivity....I can connect one of my algos to one of my Interactive Brokers accounts in about 2 minutes. Its that easy.

(3) Ability to license....Many of the systems I have developed over the last couple of years and submitted to the AlphaStreams marketplace are being licensed. Like any other endeavor in life - this takes hard work and a lot of effort.

I have had no problems with backtest times - but obviously the times will depend on the amount of data being crunched in the background.

So Im very happy - a friendly bunch of people doing real innovative stuff. I cant wait what the next few years bring!

Cons:

- lack of transparency (deleting critical statements in forum)
- alpha market is a joke. there are no trading firms paying license fees for algos.
- many alphas in market are likely overfitted
- setting up LEAN for local machine is buggy and complicated
- unnecessarily complex API, difficult to learn, poor docs (at least for python developers), LEAN is C# but most users need Python
- research (notebook) is slow, throwing time out errors when analyzing large datasets
- backtesting is slow when trading many assets with high resolution data, throwing time out errors all the time
- web ide limited, poor debugging tool
- switching between local (Skylight) and cloud is tiresome, no efficient workflow for algo development
- limited possibilities to analyze and visualize backtest results
- buggy API, bugfixes take too much time
- expensive for retail/invididuals (default pack = +800$/year)

Pros:

- community provide support in forum
- open source (LEAN)
- large and reliable database including tick data for many securities
- L1 quote data available for equities
- live trading
- event-driven backtesting engine
- all-in-one ecosystem (research, backtest, live trading, data, optimization)

Shady site not sure if the team behind are trustworthy with holding your algos data. I found other frameworks like backtrader that are easier to pick up and get working with quickly than LEAN. LEAN is poorly documenting making learning a huge hurdle. Also, I question the stability of their site because of the amount of bugs you can find in their UI and some that I encountered in plotting during backtrading. If you need an online IDE, Quantopian is far more reliable and documented and quicker to work with but still could have issues with data privacy.
