Abstract in Portuguese
A teoria da Informação nos ensina que a entropia é essencial para transmissão de informação. Considerando a eficiência informacional do mercado, assumimos que o preço de um determinado ativo objeto reflete toda informação que chega ao mercado e levando as distribuições de probabilidade de seus retornou serem ajustadas ao risco. Este trabalho aplica o tratamento entrópico para o mercado de taxa de câmbio brasileiro e sugere um modelo com probabilidades calibradas entropicamente a partir de contratos futuros de dólar que possa ser utilizado para a avaliação de estratégias de operações de opções de dólar permitindo detectar distorções entre os mercados de futuros e de opções de taxa de câmbio

Abstract in English
The Information theory teaches that entropy is fundamental to transmission of information. Considering the operacional efficiency of price we have assumed that informational effciency of market prices adjusts the distribution probabilities of return prices to a risk-neutral in an Arrow-Debreu economy. This work apply the entropic theory for the Brazilian FX market and suggest an entropic adjusted probabilities model using the FX future contracts. This model can be used to evaluate the FX option strategies and analyze mismatches between FX future and FX option contracts
