Another big flash crash seems quite unlikely to me, but what are potential trigger events for the next one (where liquidity dries up and stop loss orders aren't filled, e.g. CHF pairs on 15/1/15)?
Is there any other way a central bank could trigger a big flash crash besides pegging and unpegging their currency?
These obvious events may have warnings several days/months/years beforehand:
A comet hitting any of the major currency's country
A super volcano erupting in any of the major currency's country
A nuclear attack
An almost complete alternative to oil is invented and accepted by consumers (good bye USD as reserve currency?)
