Wagers and trading

I had an idea for FC 27;

Introduce back trading and wagers: however the trading can only work via same market price it should be around the range of 1-3% difference.

Example a single player could be worth 1m and to trade with an existing player who offers a couple of players all adding up to the market value about 1m. The trade can be accepted or declined by the user. This would also negate the use of farming or coin stacking etc.
