- Ability to re-negotiate a 'buy' or 'sell' contact after a period of time. Hypothetical example: I have a buyer from a month ago who didn't stay in touch, and now they want to buy. But the contact is fixed at the rate it was a month ago, and doesn't reflect market prices. I'd love to have the option to update the request without cancelling and having the buyer/seller re-send the request.
I had a similar idea, but almost backwards from yours. When a contact is made, the rate
equation should be locked in place, but the rate itself should keep fluctuating until the buyer and seller both choose to lock the price, at which point the escrow process begins.
