Quote from MGJ:
Please feel free to write letters to the exchanges, requesting variable contract sizes. Send emails, make phone calls, transmit faxes too. Here in the US we have a communication method called a "Candy-Gram" which is a telegram that is affixed to a 2-lb box of chocolates; if they are available in the UK, feel free to send some of those too.
Certainly the exchanges will be only too eager to create new products once they are made aware of the huge pent-up demand. In your letters / faxes / email communiques, be sure to provide estimates of the amounts of new business these products will generate (i.e. PROFITS to the exchange), and be sure to express it as a percentage so that even a dunce can understand. For example: "This will result in 50% more contracts traded, and since the new smaller contracts will be, on average, 1/5th the size of the existing contracts, 10% more Pounds Sterling of notional value changing hands".
Thanks MGJ for your comments.
In UK 100-200 spreadbet firms are making lot of money. So it might be possible for Exchanges to justify and introduce this idea. When they started E-minis same argument might have been put. This is just a thought
Best wishes for rapid success!
