correct, the difference between $5 spread and $30 is the speed of decay because of the long legLittle dog tried but margin was through the roof (3000) per Contract. But the tradeoff is much higher % OTM approaching 90+% OTM.
But it's the planning that count. I can do a $5 spread and keep the same strikes. Less winning but almost same risk level. Don't approach it from an income point of view like Yoona said - that's hard to do sometimes.....
ie $30 will reach 50% profit way earlier than the $5 does (more chances of 2nd round) and less chance of max loss due to higher breakeven point
