# Auto-exchange mechanism
When one of the auto-excange conditions is breached, the system will forcefully convert other tokens into T by relying in external ‘auto-exchangers’ who receive a discount over market price as incentive. The amounts available will take into account both the amounts in the T-bubble, as well as those that can be moved from other bubbles.
The amount of collateral $$m$$ of token $$S$$ the auto-exchanger receives in exchange is computed as
$$
(1-\mathrm{discount}*{S/T})X*{S/T}\times m=n
$$
where both $$\mathrm{discount}*{S/T}$$ and $$X*{S/T}$$ will generally be a compound term, computed as products/quotients of the official pool discounts and exchange rates (one needs to trace the S→T path on the directed graph).
The following diagram illustrates the general flow.
