I am playing with an algo that uses XIV, EDV and TMF in a small universe of equities. unfortunately They are relatively new etfs (2010, 2007 and 2009 respectively) and I would like to backtest further.
Does anyone have etf recommendations that have earlier inception dates that behave similarly and have reasonable volumes?
I have a couple of purposes;
1) Backtest earlier.
2) See if the algo is over tweaked to these specific securities.
