Best way to introspect or explore/browse Python Object when working with QC Algorithms?

Best way to introspect or explore/browse Python Object when working with QC Algorithms?

Like something similar to JSON.stringify in Javascript.  I tried str(Data) and str(OrderTicket) but all I got was nicer strings like

QuantConnect.Data.Slice

<main.CurrPairs object at 0x7fe73e04fc18>

OrderId: 1 (BrokerId: 1) Filled Market order for 1000 units of EURGBP

 

How best to debug Algo execution/backtest?  How to set breakpoints and data watch?  Any tutorials for that?   How to step-into and continue?  Also, it seems there is one minute maximum timelimit for waiting..  Am I missing something? 

PS:  I am using python as prefered language.

 

Thank you in advance.

Hey Shailesh,

The QuantConnect IDE actually has a built-in debugger. You can find it on the top right hand corner of any project open in the IDE. Here you can set breakpoints by clicking to the left of the line number you want to break at. You can also watch any variables of interest by placing them on the watchlist.
