Looks like he didn't do just naked shorts. He did short strangles. So he should've made some money on the short puts. How could he wipe out all of the accounts' money?

So if they are priced purely by vega, why did he do short strangles? If he had just done one side, just short the calls, this client in the spreadsheet would've just $800K but because he also shorted shorts, the guy lost another $800K for a total of $1 million!!!
