Forum:Cold wave & limiter overload

First, I activate cold wave. (as my first action after entering main phase 1) Next, I discard 1 card from my hand to the graveyard - "limiter overload" as a cost to special summon "The Tricky" by its built in special summon ability. The text on limiter overload reads as follows.."When this card is sent to the Graveyard, Special Summon 1 "Speed Warrior" from your hand, Deck, or Graveyard." Can I use the effect of Limiter Overload to special summon 1 Speed Warrior while cold waves effect is being applied since it is not a spell / trap that I can "activate", but instead a trigger effect which activates itself for its effect upon being sent to the grave?? (since, based on the language of the text, this appears to be a compulsory effect and I would not miss the timing)
