![]() ![]() The two converging lines will further confine the price action until there is a bearish breakdown or bullish breakout. The rising wedge pattern is the former, which is typically associated with downtrends and bearish results. The wedge is a triangle-like pattern where a resistance and support line rise or fall to converge into the shape of a wedge. What Is A Rising Wedge Pattern And How Does It Work? We’ll also provide tips on how to prepare for the rare event where a rising wedge has a bullish breakout. This guide will provide examples of a rising wedge in an uptrend and a rising wedge in a downtrend, along with how to trade them. ![]() Still, no chart pattern is reliable all the time. Certain characteristics that fit the profile of a bearish rising wedge pattern can help traders and analysts validate the pattern and increase the probability of success. The rising wedge chart pattern is a bearish pattern, but does occasionally break up to keep traders on their toes and guessing. Few trading patterns are as easy to identify and trade as the rising wedge pattern. (2015) developed a MPS-FEM coupled method to simulate a wet drop with deformable wedge.Technical analysis patterns come in various shapes and sizes, with some being more bullish or bearish, while others are neutral. (2015) proposed a MPS and modal superposition coupled method to study the 2D flexible symmetric wedge dropping into water problem. (2014) numerically studied the water entry of spheres by MPS method and discussed the influence of the surface conditions of the solids falling into the water on the formation of the splashes. (2010) employed the MPS method to calculate the impact loads by falling flat plate with incident angles. Recently, several applications of the water entry problem based on MPS method were published. Since the pressure of fluid is computed by a semi-implicit algorithm, a relatively large size of time step can be used in MPS method. Compared to SPH method, MPS method was originally proposed by Koshizuka and Oka (1996) for incompressible flow. By choosing a sufficiently high speed of sound and a much small size of time step, it can be employed to solve water entry problem (Oger et al., 2006 Shao 2009 Liu et al., 2012 Koukouvinis et al., 2013 Ma and Liu, 2014 Amicarelli et al., 2015). The SPH method is originally developed for compressible flows by Monaghan (1994). The Smoothed Particle Hydrodynamics (SPH) and Moving Particle Semi-implicit (MPS) methods are the representative Lagrangian type mesh-less methods. Among these approaches, Lagrangian particle methods are more and more popular to free surface flow problems in the near few years. On the contrary, kinds of numerical methods based on the Navier-Stokes equation are developed and show the capability to solve the water entry problem. However, these methods are hard to describe the complex nonlinear free surface flow. ![]() ![]() Among the early established methods, theoretical approaches were much popular to solve this problem. Over the past decades, the slamming problem was commonly investigated as the similar flow of wedge entry into water (Yang and Qiu, 2012), and firstly studied by von Karman (1929) and Wagner (1932). Hence, the slamming problem is important for ship design and operation. Periodical and short duration impact loads can cause serious damage to ship structure. During ship sailing at rough sea, slamming occurs when the forefoot of ship hull rises above the water surface and then drops into water with high vertical velocity (Southall et al., 2014). ![]()
