marketEvent();   preferisci la versione A gia' presente  function priceUpdate(side, book) {

    var targetPriceLevel = context.targetPriceLevels[side];

    Helper.log('LevelChange', { lastLevel: levelDiff, priceLevel: targetPriceLevel });
    status.secondCount = 0;

oppure la versione B che ti propongo in calce ? function priceUpdate(side, book) {

    var targetPriceLevel = context.targetPriceLevels[side];
