%% Simple Moving Average Example
%
% Here is an example, demonstrating how to implement a trading
% strategy and perform analysis.
%
% This is a basic technical analysis indicator, comparing two
% different moving averages of different time periods. When the
% shorter moving average crosses above the longer moving average, a
% buy signal is executed, and when the shorter moving average crosses
% below the longer moving average, a sell signal is executed.
%
% C = Vecotr of closing prices of the asset being traded
% D = Vector of dates corresponding the to closing prices
% vector
% V1 = Vector of the calculated short period simple moving
% average
% V2 = Vector of the calculated long period simple moving
% average
% Buy_Signal = Trading instruction which executes a 'buy' trade
% Sell_Signal = Trading instruction which executes a 'sell' trade
% P_n_L = Structure containing all trade data
%
%
% Example
%
% [Algo_Performance ,Buy_Hold_Performance, P_n_L]...
% = Simple_Moving_Average_Algorithm(100,250)
load ('ftse_10yr')
% The data being used is the FTSE 100 index between '01-Jan-2001' and
% '31-Dec-2010'
C = fliplr(data(:,5)'); D = fliplr(data(:,1)'); % flip the vectors
% Calculation of Simple Moving Averages
%
% 'tsmovavg' is a built-in MATLAB function that comes with the
% 'Financial Toolbox'.
V1 = tsmovavg(C, 's', Short_MA); % Short Moving Average Vector
V2 = tsmovavg(C, 's', Long_MA); % Long Moving Average Vector
% Applying trading strategy
Buy_Signal = V1 > V2; % strategy upon which buy signals are
% executed
Sell_Signal = V1 < V2; % strategy upon which sell signals are
% executed
P_n_L = Buy_only_trade_execution_algo(C,D,Buy_Signal,Sell_Signal);
% Execute the trading algorithm
n = 10; % Length of data (years), required for analysis
% For detailed explanation on the analysis tools used to assess
% performance of a particular strategy, see 'Trade_Analysis' for more
% detail.

% The Financial Toolbox is required for Sharpes Ratio.
