Start, End and Duration of Maximum Drawdown in Python. Given a time series, I want to calculate the maximum drawdown, and I also want to locate the beginning and end points of the maximum drawdown so I can calculate the duration.
import pandas as pd import matplotlib.pyplot as plt import numpy as np # create random walk which I want to calculate maximum drawdown for: T = 50 mu = 0.05 sigma = 0.2 S0 = 20 dt = 0.01 N = round(T/dt) t = np.linspace(0, T, N) W = np.random.standard_normal(size = N) W = np.cumsum(W)*np.sqrt(dt) ### standard brownian motion ### X = (mu-0.5*sigma**2)*t + sigma*W S = S0*np.exp(X) ### geometric brownian motion ### plt.plot(S) # Max drawdown function def max_drawdown(X): mdd = 0 peak = X for ... The Maximum Drawdown Risk Management Module monitors portfolio holdings and when extended beyond a predefined drawdown limit it liquidates the portfolio.

So your total loss at the end would be 70+90=160 rupees, which results in 16% max system drawdown. In a nutshell, system drawdown is calculated on entire portfolio, while trade drawdown is calculated on a particular trade.

Apr 20, 2018 · This is by the far the best freely available article on how to build a mean reversion strategy I’ve read on the Internet – Probably a question of preference but I prefer to leave position sizing out of the equation when testing, I like to use an equal weighting scheme to use as a benchmark and run MC to determine hypothetical optimum position size based on my objective function. pandas-montecarlo is a lightweight Python library for running simple Monte Carlo Simulations on Pandas Series data.
