Is this what you are looking for:
sc.BaseData[SC_ASK_BID_VOL_DIFF_MOST_RECENT_CHANGE]: This array contains a value indicating whether the SC_ASKBID_DIFF_HIGH or the SC_ASKBID_DIFF_LOW array was most recently changed.

It will be set to 1 if the SC_ASKBID_DIFF_HIGH array at the corresponding element was most recently changed. It will be set to -1 if the SC_ASKBID_DIFF_LOW array at the corresponding element was most recently changed. When using this array in a study function, it is necessary to set sc.MaintainAdditionalChartDataArrays to 1 in the sc.SetDefaults code block.

Refer to:

ACSIL Interface Members - Variables and Arrays: sc.BaseDataIn[][] / sc.BaseData[][]
