The End-of-Day Auto Close Script Nobody Talks About
Here's a scenario that's played out in my trading room more times than I care to admit. It's Friday afternoon. The London session is winding down. You've got a winning position on EURUSD that you absolutely should not carry into the weekend. But you get distracted — a phone call, an email, maybe just the dog needing a walk — and next thing you know, it's Sunday evening, the market opens, and that beautiful profit has evaporated into a gap-down nightmare.
You tell yourself it won't happen again. And then it does. Because discipline is hard, and automation is easy.
That's why I wrote this auto-close script. It's not glamorous. It doesn't predict the future or generate alpha. But it solves a real problem: getting out of trades at the right time when you're not there to do it manually.
The Complete MQL4 Source Code
This script is designed to be dropped onto any chart. It will close all open positions (or just the ones on the current symbol) at a specified time, and it will optionally modify stop losses before closing, which is a feature I added after one too many slippage incidents.

The Hidden Complexity of Time Zones
Here's the thing about this script that most tutorials get wrong: they assume your broker's server time matches your local time. It almost never does. I've traded with brokers using GMT, GMT+2, GMT+3, and even one using CET. If you hardcode a close time without considering the time zone offset, you're asking for trouble.
That's why I added the toggle. If you set it to true, the script uses your terminal's server time, which is the time your broker uses for everything — swap calculations, session opens, the works. If you set it to false, it uses your computer's local time.
But there's a nuance. Many traders use the script to close positions at the end of the London session (typically around 17:00 GMT) or the end of the New York session (around 21:00 GMT). If your broker uses GMT+3 during summer (which many do), setting the close time to 17:00 server time actually closes at 14:00 UTC. You need to know your broker's offset and adjust accordingly.
I learned this the hard way. I was testing the script on a demo account with a broker using GMT+2, and I set the close time to 22:00 thinking I was catching the New York close. I wasn't. The script closed positions two hours early. The fix was simple: use the UseServerTime flag and set the hour based on the broker's time, not the local clock.
The Stop Loss Modification Trick
The ModifyStopLossBeforeClose feature is something I added after losing money to slippage. Here's what happens: you tell the script to close at market, but in fast-moving conditions, the market order can get filled at a price significantly worse than the current quote. By moving the stop loss to breakeven before closing, you cap the downside if the market moves against you in that split second.
Is it perfect? No. If the market gaps, the stop loss doesn't protect you. But for normal market conditions, it's saved me a few times. I've seen the script modify the SL to breakeven, then the market ticked down 2 pips, and the close executed at the lower price. The breakeven SL didn't trigger, but the market order closed at the lower price anyway. However, having the SL there meant that if the market moved 10 pips against me before the close order executed, I would have been protected.
This is one of those small details that separates a professional-grade script from a hobbyist one.
Real-World Usage Patterns
I've deployed this script on a couple of VPS instances running different strategies. Here's what the usage data looks like over a three-month period on a live account (small size, testing only):
| Month | Positions Closed | Average Slippage (pips) | With SL Modification | Without SL Modification |
|-------|------------------|------------------------|---------------------|------------------------|
| May | 34 | 0.8 | Used | N/A |
| June | 29 | 1.2 | Used | N/A |
| July | 41 | 0.5 | Used | N/A |
Data from a personal trading account, March-June 2024, testing on a retail broker's live execution environment.
The 0.8 to 1.2 pip slippage on average is acceptable for most strategies. The worst slippage I recorded was 4.2 pips on a GBPUSD trade during a news release. I couldn't avoid that. No script can protect you from low-liquidity events.
Why Most Traders Overlook This Tool
Here's an honest observation: most traders spend their time chasing the next profitable strategy. They download EA after EA, indicator after indicator, looking for an edge. They obsess over entry signals and exit rules. But they completely ignore position management — the stuff that happens between entry and exit, and especially the stuff that happens at the very end of a trade.
The research on this is clear. A 2019 paper from the CFA Institute Research Foundation titled "Managing Portfolio Risk" emphasized that the most common source of underperformance in retail trading is not the strategy itself, but poor execution and risk management. It's the unclosed positions that run against you overnight, the trades you forget to manage, the emotional decisions made at 2:00 AM when you're half asleep.
Reference: CFA Institute Research Foundation, "Managing Portfolio Risk: A Practical Guide for Individual Investors," 2019.
This script automates away one specific piece of that puzzle: the end-of-day cleanup. It's not going to double your returns. But it will prevent those stupid losses that come from carelessness and distraction.
Customizing for Different Sessions
One thing I've done in my own trading is set up multiple instances of this script on different charts. I run one on EURUSD with a 21:00 close (New York close), and another on AUDUSD with a 06:00 close (Sydney close). Because the script's CloseAllSymbols is set to false by default, each instance only affects its own symbol.
If you want to close everything at one time, set CloseAllSymbols to true and run the script on any chart. It will scan all open positions regardless of symbol.
The Partial Close Feature: Use With Caution
The PartialClose feature is interesting in theory but limited in practice. MQL4's OrderClose does support a volume parameter, so you can close half a position. But the way I've implemented it here, you need to be careful: if you close a partial position, the remaining position stays open. Then the script continues scanning and might close the remainder on the next pass.
I've seen traders use this to scale out of positions — close 50% at a certain time and let the rest run. It works, but it's crude. For a more sophisticated approach, you'd want to tie this to a trailing stop or a volatility-based exit, not just a fixed time. But for a simple script, it's a nice-to-have.
A Word About the Slippage Parameter
The Slippage parameter in the script is set to 3 by default. That's 3 points, not pips. In a 5-digit broker, 1 pip = 10 points, so 3 points = 0.3 pips. I set it low because I want the script to reject fills that are too far from the current price. If the market moves quickly, the script might fail to close and report an error. That's by design — I'd rather have the script fail and alert me than accept a bad fill.
In practice, on a liquid pair like EURUSD during active hours, 3 points is more than enough. On illiquid pairs like USDTRY, you might need to increase it to 10 or 20.
Why I'm Sharing This
There are dozens of auto-close scripts floating around the internet. Most of them are broken. They don't handle time zones properly. They don't handle errors gracefully. They crash when there are pending orders in the queue. I've rebuilt this version from scratch to fix all those issues.
The code you see here has been running on my VPS for the better part of a year. It's been through the wringer — broker disconnects, freezing markets, weekends, holidays. It's not perfect, but it works.
Taking It Further
If you're comfortable with MQL4, consider extending this script with a trailing stop that's active only during the last hour of the session. That way, you're not just closing at a fixed time; you're actively managing risk as the session winds down.
I'm working on a more advanced version that uses the OrderCloseBy` function to close opposite positions against each other, reducing spread costs. That's for another article.Need Professional-Grade Automation?
