MongoDB (MDB) is long from $24.  MongoDB stock  is trading at $38.94 as of this writing.  The company will report earnings after the close tomorrow.  Earnings represent a risk both to the upside and to the downside.  We had previously stated that it could go to $40.

It is simply prudent to book profits on one-half of the remaining position in the zone of $39 to $40.73 before the earnings.

Consider continuing to hold the remaining half.
