How to Print or Log Specific Factors and Values

Seeking Help Getting Started

In the attached algo, stocks are ranked using the following:

df['rank_long'] = df['pe_ratio'] * df['pb_ratio']

Can someone tell me how to print or log the following after each transaction?

  1. Stock symbol (currently showing up under 'Placing Order')
  2. "rank_long" value
  3. pe ratio
  4. pb ratio

Currently, the logs look like this:

2015-02-02rebalance:153INFOPlacing order: Equity(3450 [MNST])

I would like the logs to look like this (or similar as long as the data are shown):

2015-02-02rebalance:153INFOPlacing order: Equity(3450 [MNST]), rank_long=xxx, pe_ratio = xxx, pb_ratio = xxx

Edit: It looks like changing the ranking factors (pe ratio & pb ratio) do not have an impact on performance, so there must be a bust in the algo. If anyone could help a beginner out to get this working I'd appreciate it.

Thanks.

Troy

You compute rank_long from pe_ratio and pb_ratio in the function rank_long, but you never call the function. Of course the ratios will have no impact on anything if you never use them.
