<section xml:id="fut21659-sec-0001"> We develop an approximation technique for pricing finite‐maturity timer options under Heston‐like stochastic volatility models. By approximating the distributions of the accumulated variance and the random variance budget exceeding time, we obtain analytic expressions for timer option...</section>
