Historical Warrant pricing

[racemize]

I'm working on an essay on cost of leverage that is mostly done.  I'd like to show how the cost of leverage develops over time, which means I need historical warrant pricing (probably just use AIG/BAC/JPM/WFC).  Anyone know where I could get it (e.g., daily or monthly closing prices)?  Yahoo finance doesn't keep it for some reason.  About to go check out fidelity, which makes a graph, but not sure if I can get the data itself. 

 

TIA.

Fidelity had it.  Should have finished looking before asking.

Nasdaq and Marketwatch have it. Especially if you're looking for charts. Historical prices are iffy.
