Understanding their meanings can help you use EA better.<br>\nBelow is a simple explanation of several common terms:&nbsp;<br><br>\n\n<h3><strong>1. Backtesting<\/strong>&nbsp;<\/h3>\n<ul>\n <li><strong>What is it?<\/strong>&nbsp;Testing your EA strategy using <strong>historical market data<\/strong>.<\/li>\n <li><strong>Why do it?<\/strong>&nbsp;Like taking a \"historical simulation test\" to see if your strategy would have made a profit or loss in the past.<\/li>\n <li><strong>What to watch out for?<\/strong>&nbsp;Past performance does not guarantee future results; the market always changes.<\/li>\n<\/ul><br>\n\n<h3><strong>2. Optimization<\/strong>&nbsp;<\/h3>\n<ul>\n <li><strong>What is it?<\/strong>&nbsp;Adjusting various EA setting parameters to find the best combination.<\/li>\n <li><strong>Why do it?<\/strong>&nbsp;To make the EA perform best on historical data (maximizing profit or minimizing risk).<\/li>\n <li><strong>What to watch out for?<\/strong>&nbsp;Beware of \"over-optimization,\" which can make the EA too perfect for past data but unable to adapt to real markets.<\/li>\n<\/ul><br>\n\n<h3><strong>3. Slippage<\/strong>&nbsp;<\/h3>\n<ul>\n <li><strong>What is it?<\/strong>&nbsp;The difference between the expected execution price and the actual execution price.<\/li>\n <li><strong>Why does it happen?<\/strong>&nbsp;Caused by rapid price changes or insufficient market liquidity.<\/li>\n <li><strong>Is it good or bad?<\/strong>&nbsp;There can be positive slippage (better execution price) and negative slippage (worse execution price).<\/li>\n <li><strong>Can EA avoid it?<\/strong>&nbsp;It cannot be completely avoided; EA will also encounter slippage.<\/li>\n<\/ul><br>\n\n<h3><strong>4. Virtual Private Server (VPS)<\/strong>&nbsp;<\/h3>\n<ul>\n <li><strong>What is it?<\/strong>&nbsp;A remote computer that can operate 24 hours a day.<\/li>\n <li><strong>Why does EA need it?<\/strong>&nbsp;To ensure MT4\/MT5 runs continuously even if your local computer is turned off.<\/li>\n <li><strong>Benefits of using VPS?<\/strong>&nbsp;Ensures EA runs uninterrupted and stably.<\/li>\n <li><strong>Is there a cost?<\/strong>&nbsp;Usually rented monthly.<\/li>\n<\/ul><br>\n\n<h3><strong>Simple Summary<\/strong>&nbsp;<\/h3>\n\n<table border=\"1\" cellpadding=\"1\" cellspacing=\"0\" style=\"100%\">\n <thead>\n <tr>\n <th><strong>Term<\/strong>&nbsp;<\/th>\n <th><strong>Simple Explanation<\/strong>&nbsp;<\/th>\n <th><strong>Why Important for EA Users?<\/strong>&nbsp;<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td><strong>Backtesting<\/strong>&nbsp;<\/td>\n <td>Testing strategy with historical data to see past performance.<\/td>\n <td>Evaluate strategy quality and risk before using real money.<\/td>\n <\/tr>\n <tr>\n <td><strong>Optimization<\/strong>&nbsp;<\/td>\n <td>Adjust EA settings to find the best performing combination on past data.<\/td>\n <td>May improve performance but be careful not to over-optimize.<\/td>\n <\/tr>\n <tr>\n <td><strong>Slippage<\/strong>&nbsp;<\/td>\n <td>Difference between actual and expected execution price.<\/td>\n <td>Affects real profit and loss, especially during high market volatility.<\/td>\n <\/tr>\n <tr>\n <td><strong>VPS<\/strong>&nbsp;<\/td>\n <td>A continuously running remote computer used to run your trading platform and EA.<\/td>\n <td>Ensures EA runs 24\/7 without interruption, unaffected by your local computer.<\/td>\n <\/tr>\n <\/tbody>\n<\/table>\n<\/span><\/div><\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d6f0c52 elementor-icon-list--layout-inline elementor-tablet-align-center elementor-mobile-align-center elementor-hidden-desktop elementor-hidden-tablet elementor-hidden-mobile elementor-list-item-link-full_width elementor-widget elementor-widget-icon-list\" data-id=\"d6f0c52\" data-element_type=\"widget\" data-widget_type=\"icon-list.default\">\n\t\t\t\t\t\t\t<ul class=\"elementor-icon-list-items elementor-inline-items\">\n\t\t\t\t\t\t\t<li class=\"elementor-icon-list-item elementor-inline-item\">\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/www.mql5.com\/en\/users\/sagen520\/seller\" target=\"_blank\" rel=\"nofollow noopener\">\n\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-icon\">\n\t\t\t\t\t\t\t<svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-link\" viewbox=\"0 0 512 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M326.612 185.391c59.747 59.809 58.927 155.698.36 214.59-.11.12-.24.25-.36.37l-67.2 67.2c-59.27 59.27-155.699 59.262-214.96 0-59.27-59.26-59.27-155.7 0-214.96l37.106-37.106c9.84-9.84 26.786-3.3 27.294 10.606.648 17.722 3.826 35.527 9.69 52.721 1.986 5.822.567 12.262-3.783 16.612l-13.087 13.087c-28.026 28.026-28.905 73.66-1.155 101.96 28.024 28.579 74.086 28.749 102.325.51l67.2-67.19c28.191-28.191 28.073-73.757 0-101.83-3.701-3.694-7.429-6.564-10.341-8.569a16.037 16.037 0 0 1-6.947-12.606c-.396-10.567 3.348-21.456 11.698-29.806l21.054-21.055c5.521-5.521 14.182-6.199 20.584-1.731a152.482 152.482 0 0 1 20.522 17.197zM467.547 44.449c-59.261-59.262-155.69-59.27-214.96 0l-67.2 67.2c-.12.12-.25.25-.36.37-58.566 58.892-59.387 154.781.36 214.59a152.454 152.454 0 0 0 20.521 17.196c6.402 4.468 15.064 3.789 20.584-1.731l21.054-21.055c8.35-8.35 12.094-19.239 11.698-29.806a16.037 16.037 0 0 0-6.947-12.606c-2.912-2.005-6.64-4.875-10.341-8.569-28.073-28.073-28.191-73.639 0-101.83l67.2-67.19c28.239-28.239 74.3-28.069 102.325.51 27.75 28.3 26.872 73.934-1.155 101.96l-13.087 13.087c-4.35 4.35-5.769 10.79-3.783 16.612 5.864 17.194 9.042 34.999 9.69 52.721.509 13.906 17.454 20.446 27.294 10.606l37.106-37.106c59.271-59.259 59.271-155.699.001-214.959z\"><\/path><\/svg>\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-text\">Mr.Forex has listed an Expert Advisor (EA) on MQL5.
