Why Does Your MT4 EA Show Different Colors on the Chart—and What Does That Actually Mean?

If you've ever glanced at your MT4 chart after an Expert Advisor (EA) places a trade and noticed a tiny blue or red arrow marking the entry point, you've probably wondered: why those colors? Some traders assume the arrow color reflects whether the trade is winning or losing. Others believe it signals a specific strategy condition being met. But the truth is surprisingly straightforward—and understanding it might change how you think about monitoring your open positions.

The Short Answer: It’s Just the Entry Direction

In MT4, when an EA opens a trade using the OrderSend() function, the final parameter specifies the color of the opening arrow drawn on the chart . A blue arrow typically marks a Buy order, while a red arrow marks a Sell order . That's it. The color doesn't indicate profit, loss, trend strength, or any clever signal. It's a purely visual cue baked into the platform's legacy design—in fact, "it's not related to trading at all" in the sense of strategy logic .

So If the Arrow Doesn't Tell You Much, What Should You Actually Watch?

Here's where many traders hit a wall. The arrow appears briefly as a historical mark in the chart window. To get a real picture of your current open positions—their actual profit/loss, which direction you're exposed to, and whether a position is worth keeping or closing—you still have to open the full MT4 terminal, dig into the "Trade" tab, and scan through rows of numbers. If you're running multiple EAs or managing several pairs, that means constant window switching and distraction.

This gap—between quickly seeing that a trade happened and actually managing it without interrupting your workflow—is where tools like Camovia Tray come into the picture. Camovia Tray turns MT4 into a system tray tool, letting you view open positions with key details—symbol, direction, lots, open price, and current P&L—without ever bringing the main MT4 window to the foreground . Need to close a losing position fast? The floating order panel lets you do it with two confirmation clicks, right from the tray . It's not about replacing your EA's logic—it's about making what happens after the trade opens more accessible and less distracting.

A Quick Note on MT5 (and Why Color Works Differently There)

If you're running an EA on MT5, you won't see the same colored arrow behavior for trades. The MqlTradeRequest structure in MT5 doesn't include an arrow color parameter at all—trading operations are completely decoupled from chart visuals . The MT5-style OrderSend from third-party libraries might mimic MT4 behavior for compatibility, but it's not native . This distinction matters if you rely on visual trade markers; you may need a different habit to confirm entry points in MT5.

The Real Takeaway: Don't Mistake Visual Cues for Actionable Data

An EA's arrow color is a convenient reminder that a trade was placed—but it's just that, a reminder. To actually manage risk, check floating P&L, or close a position before a reversal, you need to step outside the chart and into your trade management routine. If that routine feels clunky or pulls you away from what you're doing, you're not alone. Camovia Tray aims to solve that friction by making position monitoring and management a lightweight, always-accessible part of your desktop—so you can stay focused on strategy, not on hunting through terminal tabs.
