TSLA call options price difference?

L

Lucsan001

I was looking at the option chain for TSLA contracts that ended yesterday 17th and I was shocked to see how different the options contracts were worth at expiration. Why did the $385c stay the same? And also the real question irking me, why the $475c was the only contract to lose money(-$4) and why the $525c gained a massive $18 a contract?

From the screenshot, looks like you’re looking at the $change from the previous day’s price, but that’s invalid because the previous day’s price isn’t known. It’s only derived from the last sale price (yesterday) which could’ve happened any time during the previous day, or even several days earlier if it wasn’t traded often. Those prices don’t really mean much.
 
Looks like you are trading thru TOS..Their closing marks are all over the map. Meaningless...

You can monitor it by looking at you Net Liquidating Value

I took this screenshot last night after the market had already closed. From this screenshot under Net Change, doesn’t this mean how much each contract gained in value?

Yes, how much it gained in value from an unknown value, as I explained above.
Brokers cannot know what was its previous value except for some old price that could be days old.
 
Lucsan001-You will have to ask TDA if that value is the change from the last sale on any day to the last sale on that day or some other metric. The reality is that this column does not provide real actionable information on deep ITM options that do not trade all day and when the last sale does not represent the current market because the last sale could have been days ago. For myself, I would be more apt to follow changes in IVOL with ATM options from one day to another or overtime. The next metric I find value in is the option skew. I like to follow the 25 delta call and 25 delta put. Following the (put-call) gives a metric to watch that shows changes in supply-demand for puts over calls. I find this has more value with options that are not short term in nature like less than 1 week.

Ok, I get it now for some reason I kept thinking that that was the total gain on the contract. Thanks for the info.
