Ok but you said there was more liquidity on tt than the broker mkt....that is false....i asked you to tell me the contract so i could check tick data and u failed to do so...at the time your claim on spark spread was made, the rules on swaps and elegible contract particiants would make it impossible for you to trade it as it was still a 100% voice broker swaps dominated market....even til thisdl day i cant find an electronic spark spread contract...so i can imagine 5 years ago....just bc it is listed by Tt and the exchange doest make the contract active...
