I need to select a table so that only the first (earliest by date) OT row is selected when the previous value for the OT is the same.

ST the OT in date order should always be 1,2,1,2...

The entire table should be:

symbolDate                       OT   Quantity VPrice LastPrice  IDNO  interID

BIndex2014-01-17 09:33:03.53172511     1      0     2896   4958   60

BIndex2014-01-17 10:12:01.79110861     1      0     2890   4960   60
