Hi Inrina, Thanks for your reply. I am aware that FpML covers Asian Equity Options. My understanding about Rainbow Asians is limited at this point and I am trying to get more insight from one of our groups. I understand it has a matrix (as opposed to a list) of averaging dates based on the number of baskets, with weights. As well there is initial and final averaging. I have sent a request to get some sample confirmations and I will provide them when I receive it. Thanks, Eli
