On adding or editing a speciality you will need to define the main value(s) of shema(s) you've selected. A candlestick and a bar chart for each schema will be shown to you with the last 30 days swing and volume transactions so that you can select a resonable value for each.
At the side, a speciality with a Fix payment schema with a fix payment of 10.0 is being edited. It is being shown the fix payment' swing of the last 30 days and beneth it the number of transaction on each day. The initial value of 10.0 was resonable or "in market" at the beginning but become unresonable or "off market" as the parameter value decline with time.
