This thesis is about stochastic approximation analysis and application in Finance. In the first part, a convergence result for stochastic approximation where the innovations satisfy averaging assumptions with some rate is established. It is applied to different types of innovations and illustrated on examples mainly motivated by Finance. A result on "universal" rate of convergence is then presented when the innovations are uniformly distributed and compared to those obtained in the i.i.d. framework. The second part is devoted to applications. First an optimal allocation problem applied to dark pools is studied. The execution of the maximum of the desired quantity leads to the design of a constrained stochastic algorithm studied in the i.i.d...
