Tcs orders always store prices in a fixed "sell per buy" style, but users
can create them in either price direction. When they look at them later,
the ui needs to know what their preferred style is for this order.
To have more precision when storing user supplied prices and ensure that
the rounding that will occur will be tiny compared to the user-provided
precision.
Users can request token swaps to happen when the oracle price
is within a price band. Once the price is right, an executor can
trigger the swap. The executors are rewarded with a premium
over the oracle price.
This allows limit and stop loss orders on arbitrary spot pairs.
The PR comes with basic ts support and adjustments to the liquidator,
to execute available token conditional swaps.
