_calcShiftingDone

This function calculates the new value of a parameter after a shifting process.

function _calcShiftingDone(uint256 current_, uint256 old_, uint256 timePassed_, uint256 shiftDuration_)
    internal
    pure
    returns (uint256);

Parameters

Name	Type	Description
current_	uint256	The current value is the final value where the shift ends
old_	uint256	The old value from where shifting started.
timePassed_	uint256	The time passed since shifting started.
shiftDuration_	uint256	The total duration of the shift when old_ reaches current_

Returns

Name	Type	Description
<none>	uint256	The new value of the parameter after the shift.

_calcRangeShifting

This function handles the gradual shifting of range values over time

If the shift is complete, it updates the state and clears the shift data

Calculates the new upper and lower range values during an active range shift

function _calcRangeShifting(uint256 upperRange_, uint256 lowerRange_, uint256 dexVariables2_)
    public
    _onlyDelegateCall
    returns (uint256, uint256, uint256);

Parameters

Name	Type	Description
upperRange_	uint256	The target upper range value
lowerRange_	uint256	The target lower range value
dexVariables2_	uint256	needed in case shift is ended and we need to update dexVariables2

Returns

Name	Type	Description
<none>	uint256	The updated upper range, lower range, and dexVariables2
<none>	uint256
<none>	uint256

_calcThresholdShifting

This function handles the gradual shifting of threshold values over time

If the shift is complete, it updates the state and clears the shift data

Calculates the new upper and lower threshold values during an active threshold shift

function _calcThresholdShifting(uint256 upperThreshold_, uint256 lowerThreshold_, uint256 thresholdTime_)
    public
    _onlyDelegateCall
    returns (uint256, uint256, uint256);

Parameters

Name	Type	Description
upperThreshold_	uint256	The target upper threshold value
lowerThreshold_	uint256	The target lower threshold value
thresholdTime_	uint256	The time passed since shifting started

Returns

Name	Type	Description
<none>	uint256	The updated upper threshold, lower threshold, and threshold time
<none>	uint256
<none>	uint256

_calcCenterPrice

This function gradually shifts the center price towards a new target price over time

It uses an external price source (via ICenterPrice) to determine the target price

The shift continues until the current price reaches the target, or the shift duration ends

Once the shift is complete, it updates the state and clears the shift data

The shift rate is dynamic and depends on:

• Time remaining in the shift duration

• The new center price (fetched externally, which may change)

• The current (old) center price

This results in a fuzzy shifting mechanism where the rate can change as these parameters evolve

The externally fetched new center price is expected to not differ significantly from the last externally fetched center price

Calculates the new center price during an active price shift

function _calcCenterPrice(uint256 dexVariables_, uint256 dexVariables2_)
    public
    _onlyDelegateCall
    returns (uint256 newCenterPrice_);

Parameters

Name	Type	Description
dexVariables_	uint256	The current state of dex variables
dexVariables2_	uint256	Additional dex variables

Returns

Name	Type	Description
newCenterPrice_	uint256	The updated center price
