Okay, here's a breakdown of what this MetaTrader script does, explained in a way that doesn't require any programming knowledge:
In a Nutshell
This script is designed to automatically place a series of buy and sell orders, creating a "grid" or "mesh" of potential trades. It's like setting up a fishing net to catch price movements in either direction. The idea is that as the price fluctuates, some of these orders will be triggered, and the script will try to manage them to make a profit.
Key Concepts
- Grid: Imagine a series of lines, each representing a price level. At each of these lines, the script can place either a buy order (betting the price will go up) or a sell order (betting the price will go down). The distance between these lines is the "Grid Size".
- Orders: These are instructions to your broker to buy or sell a currency pair when the price reaches a certain level.
- Expert Advisor (EA): This is the Metatrader term for a script that can execute trades automatically.
How it Works
-
Setup: When you attach this script to a currency chart, you can adjust several settings:
- Lot Size: How big each trade will be.
- Grid Size: How far apart the orders in the grid will be (in pips, a unit of price movement).
- Number of Steps: How many orders to place above and below the current price.
- Take Profit: How much profit (in pips) the script should aim for before closing a winning trade.
- Stop Loss: The maximum loss (in pips) the script should tolerate before closing a losing trade (though this script is designed to not use a stop loss).
- Magic Number: A unique ID that helps the script identify its own trades and not interfere with other automated strategies.
- Trading Style: You can choose whether to place buy orders above the current price and sell orders below (breakout), or vice versa (counter).
-
Placing Orders:
- The script calculates a series of price levels based on the grid size and the current price.
- At each price level, it can place either a buy order or a sell order, depending on its settings.
- The orders are initially "pending," meaning they will only be activated if the price reaches that level.
- The script can be configured to consider market trends and only places orders if the trend matches the grid.
-
Managing Trades:
- Take Profit: When a trade becomes profitable, the script automatically closes it when the profit reaches the specified "Take Profit" level.
- Trailing Stop: The script can be set to automatically adjust the stop loss as the price moves in a favorable direction, locking in profits.
- Breakeven: The script can move the stop loss to the entry price after the price has moved a certain number of pips in a favorable direction, ensuring that the trade cannot result in a loss.
- Time Limit: The script can be set to close all open orders and positions after a certain period of time, ensuring that the grid does not remain open indefinitely.
-
Filters and Conditions:
- EMA Filter: The script can be set to only place buy orders above a certain price level (an Exponential Moving Average, a type of trend indicator) and sell orders below it. This is intended to align the grid with the prevailing trend.
- MACD/OsMA Filters: The script can use MACD or OsMA (other trend indicators) to determine whether to allow buy or sell orders. It can also close existing orders or positions if the MACD or OsMA signals a trend reversal.
- Profit Target: The script can be set to close all positions once a certain profit target has been reached.
Important Considerations
- Risk: Grid trading can be risky because it involves placing multiple orders without a fixed stop loss. If the price moves strongly in one direction, losses can accumulate quickly.
- Market Conditions: Grid trading works best in ranging or sideways markets. It can be less effective in strongly trending markets.
- Broker Requirements: Some brokers may have restrictions on the number of open orders or the minimum distance between orders.
In Simple Terms
The script is like a robot that automatically sets up a series of bets on whether the price will go up or down. It tries to catch price movements and close trades for a small profit, while also having some safeguards in place to limit losses. However, it's crucial to understand that grid trading involves risk, and this script should be used with caution.

// DISCLAIMER ***** IMPORTANT NOTE ***** READ BEFORE USING *****
// This expert advisor can open and close real positions and hence do real trades and lose real money.
// This is not a 'trading system' but a simple robot that places trades according to fixed rules.
// The author has no pretentions as to the profitability of this system and does not suggest the use
// of this EA other than for testing purposes in demo accounts.
// Use of this system is free - but u may not resell it - and is without any garantee as to its
// suitability for any purpose.
// By using this program you implicitly acknowledge that you understand what it does and agree that
// the author bears no responsibility for any losses.
// Before using, please also check with your broker that his systems are adapted for the frequest trades
// associated with this expert.
// 1.8 changes
// made wantLongs and wantShorts into local variables. Previously, if u set UseMACD to true,
// it did longs and shorts and simply ignored the wantLongs and wantShorts flags.
// Now, these flags are not ignored.
// added a loop to check if there are 'illicit' open orders above or below the EMA when the limitEMA34
// flag is used. These accumulate over time and are never removed and is due to the EMA moving.
// removed the switch instruction as they dont seem to work - replaced with if statements
// made the EMA period variable
//
// 1.9 changes - as per kind suggestions of Gideon
// Added a routine to delete orders and positions if they are older than keepOpenTimeLimit hours.
// Added OsMA as a possible filter. Acts exactly like MACD.
// Added 4 parameters for MACD or OsMA so that we can optimise
// Also cleaned up the code a bit.
// 1.92 changes by dave
// added function openPOsitions to count the number of open positions
// modified the order logic so that openPOsitions is not > GridMaxOpen
// 1.93 added long term direction indicator
// Added tradeForMinutes - will only trade for this time then stop till EA is reset.
