buggy, slow, opaque, poor docs and expensive
cannot recommend
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)
