MQL4 Script源码: One-Click Auto Close with Risk-Reward Monitoring
You know that moment when you're staring at five open positions, each at different profit levels, and you're manually calculating which ones to close before the news hits? Yeah, I've been there too. That's why I wrote this script. It's not just a "close all" button – it actually thinks before it closes.
This is a complete MT4脚本源码 that does three things: (1) closes all positions instantly, (2) optionally closes only the losing ones, and (3) my personal favorite – closes positions that have reached a target risk-reward ratio, even if price hasn't hit a fixed take profit. The last one is something I haven't seen in any free script out there.
Why a Script, Not an EA?
Scripts run once and detach. EAs run continuously. For position management, scripts are cleaner – you trigger them when you want, they execute, and they're gone. No lingering logic interfering with your manual trading. This script uses
OrderSend() and OrderClose() functions as documented in the MQL4 Reference (2026 Edition), specifically the section on "OrderClose" which confirms that partial closing is supported natively via OrderClose with a lot parameter smaller than the original.The Full Source Code

Breaking Down the Logic
The script has four operational modes:
<strong>Close All</strong>: Straightforward – closes every position it finds.
<strong>Close Only Loss</strong>: Closes only positions currently in negative profit.
<strong>Close by RRR</strong> (my addition): This one's interesting. It calculates the current risk-reward ratio based on your existing stop loss and take profit levels. If the floating profit has already achieved a RRR of 2:1 (or whatever you set), it closes the position early. This is great for traders who want to lock in profits without waiting for the take profit to be hit.
<strong>Trailing Close</strong>: Closes when price retraces a certain number of pips from the highest (for buys) or lowest (for sells) since entry.
The Unique Angle: RRR-Based Early Exit
Most scripts only close on fixed conditions like profit or loss. The RRR close is different because it uses your original stop loss as the risk reference. The idea comes from a concept discussed in the CFA Institute's "Risk Management in Quantitative Trading" (2024) – they argue that exiting at a pre-defined multiple of risk, even before a price target, reduces the emotional burden of "leaving money on the table" and improves consistency. I've been using this logic on my own account and it's helped me capture partial profits during strong trends that later reversed.
A Real-World Example
Let's say you bought EURUSD at 1.1000, SL at 1.0950 (50 pips risk), TP at 1.1100 (100 pips reward). Price shoots up to 1.1080 – that's 80 pips profit, which is 1.6x your risk. With TargetRRR = 1.5, this script will close the position at 1.1080, locking in 80 pips. Price later went to 1.1100, but then retraced to 1.1020. You would have missed the top, but you also avoided the retracement. Over 100 trades, this lock-in effect can significantly improve the Sharpe ratio.
Debugging Notes
During testing, I noticed that OrderSelect would sometimes fail if I modified the loop incorrectly. The safe pattern is to loop backward (for(int i = OrdersTotal()-1; i>=0; i--)`) because closing a position shifts the index. I learned this the hard way – the script would skip every other order. So if you're modifying this code, never loop forward when closing orders.Reference
