Thanks for your thoughts!
I will be adding a page or two with combined charts. Personally I find myself looking at the total swap sums vs price quite a lot recently (even without a combined chart) The sum tells me a bit about the market sentiment. If the total USD sum rises a lot, traders feel bullish and it's a nice indicator of where the price will go for a while. The other way around if the sum of BTC / LTC swaps increases suddenly, traders are shorting and expect the prices to drop for a while. Please let me know what other combinations you all like to see.
I'll add Nick's and Tsay's request and also my sum vs price (probably combined with average rate as an option) idea.
What other charts / tables you all would like to see added? Let me know here and share your thoughts like Nick and Tsay on why it is useful. Good ideas will be rewarded with a nice chart
