Algo Scoring and Preferences in Holding Periods

Back

Hi everyone,

 

I'm new to the community and I've looked through the Algorithm Scoring documentation but the mentions of time frame are somewhat ambiguous.  So I'm curious, is holding period a factor in scoring?  I understand there are many different ways to trade and different time scales to trade on but it seems like the holding period could be a valuable scoring component.  Am I missing something?  Is the method used for scoring algorithms holding period invariant?

 

I'm also curious if anyone has any thoughts on selecting a holding period for certain strategies?  I figure strategies involving fundamentals are more useful for a longer holding period, but I see how fundamental factors could be used to supplement a mean reversion or momentum strategy in a shorter term.

Hi,

There are two types of scores:

  • Direction score - when your buy (sell) insight closed, was the security higher (lower) than when you issued the insight? (binary yes/no)
  • Magnitude score - when your insight closed, had the security moved by as much as you had predicted? (continuous 0->1)
Neither of these have any dependency on holding period per se - aside from that they are calculated when the holding period has expired.You raise a good point - holding periods should perhaps be a more direct factor in the scoring. However, this is taken care of by the Terminal's advice on your alphas: it tells you whether you have a sensible number of trades per year, which should be inversely proportional to your holding period (roughly).
