I'm just pulling this info from TOS at the moment:
June
1 sigma = 1224/1299
2 sigma = 1190/1337
July
1 sigma = 1194/1335
2 sigma = 1130/1409
vol = 18.14%
You can also do a rough calculation by taking the ATM strangle for 1 sigma, doubling it to get 2 sigma.
Can you tell me where on the TOS software you are pulling this, I have TOS
Thanx for your help!
