Abstract: Trailing stop is a popular stop-loss trading strategy by which the investor will sell the asset once its price experiences a pre-specified percentage drawdown. x��Mw7��JK���9�-����Z�l�f,���Y͑�8�9'vƙeK������NL%����G����ainX /BitsPerComponent 8 One of the investor can buy or sell the contact with the agreed price (strike price) during the agreed time period (exercise time).

(Motivation) Typically used for controlling risk, stop loss orders may actually increase long-run trading profit. a procedure for determining the optimal trading rule (OTR) without running alternative model configurations through a backtest engine. Balancing the amount of risk either in a dollar figure or a pivotal price can be daunting. The balance is to spend enough time to ensure finding as optimal of a choice as the problem requires, but no more than that.

A class of recursive optimal stopping problems with applications to stock trading Katia Colaneri Vienna, 24 May 2019 joint work with Tiziano De Angelis. Optimal stopping problems consider the question of deciding when to stop an observation-generating process in order to maximize a return. Optimal selling rules in a regime switching.

Lecture 16 - Backward Induction and Optimal Stopping Times Overview. endobj Typical reward:risk ratios are between 1.5:1 and 3:1 when day trading. In a multi-dimensional Markovian setting we show that the problem is well posed, in the sense that the value is indeed the unique solution to a fixed point problem in a suitable space of continuous functions, and an optimal stopping time exists.

Since stopping rule problems are defined by the sequences (i) and (ii) of §1.1, we must specify in each case the observations, X 1,X 2,..., their joint distributions, and the reward (or cost) function, y n(x 1,...,x n) for stopping at stage n. We often use Y trading Problem #3 - Letting small losses turn into big losses As I just mentioned, trading stocks is a probability game. Advances in Applied Probability, 2(2), 259–286.

Finally we apply our class of problems to a model for stock trading in two different market venues and we determine the optimal stopping rule in that case.

(The general case) We first define the optimal liquidation premium that represents the additional value from optimally waiting to sell, as opposed to immediate liquidation. endobj We present empirical evidence of the existence of such optimal solutions for the case of prices following a discrete Ornstein-Uhlenbeck process, and show how they can be computed numerically. endobj Englewood Cliffs, NJ: Prentice Hall. In probability theory, the optional stopping theorem (or Doob's optional sampling theorem) says that, under certain conditions, the expected value of a martingale at a stopping time is equal to its initial expected value.

Therefore, we design a backward recursive algorithm computing the value function to determine the stopping boundary. Threshold strategies are among the most important and common strategies for one-dimen-sional optimal stopping problems, although there are simple examples for which the optimal stopping decision is not of threshold type; see, for example, [4].
