Right, so if stock has $1.00 strikes, I want to see horizontal lines $1.00 apart, but if it has $2.50, I want to see them $2.50 apart.
I think you may have to do it manually for every symbol. In chart settings you can do a custom interval and the custom prices can be set for any interval desired. Unfortunately, I don't think there's anything that will do it automatically based on strike. But I could definitely be wrong.
