Trading from your phone means you're often away from the full desktop terminal — but a stop loss still needs to be set the moment you enter. Here's exactly how to do it on the MT5 mobile app for both iPhone and Android, with no guesswork.
Setting a Stop Loss on a New Mobile Order
- Open the app and tap the Quotes tab.
- Tap the symbol you want to trade, then tap Trade (or "New Order").
- The order screen shows volume, plus optional Stop Loss and Take Profit fields.
- Tap the Stop Loss field, type your price, and tap done.
- Choose Buy or Sell. The stop loss is attached from the first second.
If the Stop Loss field is empty when you open the screen, tap it and enter a value — the app will show an error if the price is on the wrong side of the market.
Adding a Stop Loss to an Open Position on Mobile
- Tap the Trade tab at the bottom to list your open positions.
- Tap the position once to select it.
- Tap the pencil (edit) icon at the bottom, or long-press the position and tap Modify.
- Enter your level in the Stop Loss field and confirm (usually a checkmark or "Done").
Both iPhone and Android follow the same flow; the only difference is the placement of icons, which is nearly identical between the two.
Modifying or Removing a Stop Loss on Mobile
- To move a stop loss, open the same Modify screen and type a new price, then confirm.
- To remove it entirely, clear the Stop Loss field (delete the number) and confirm.
There's no "cancel stop loss" button — clearing the field is how you remove it. The position stays open; only the protective order goes away (which is usually a bad idea, so think twice).
Why Mobile Traders Miss Their Stop Loss
The most common mistake on mobile is executing in a hurry: you see a move, tap Buy, and skip the Stop Loss field entirely. The fix is a pre-trade habit — decide your stop price and lot size before you open the order screen, then fill both fields in together.
Mobile Stop Loss Tips for Prop Firm Traders
- Always pre-calculate risk: a stop loss alone doesn't protect you if your lot size is too big. Size the trade so a stop-out costs ~1% of the account.
- Use pending orders when possible: if you can't watch the screen, place a limit or stop order with the stop loss already attached.
- Double-check before confirming: on a small screen it's easy to fat-finger an extra zero. Read the number twice.
A Worked Example: Quick Stop on Your Phone
You're long one lot of GBP/USD at 1.2700 from your phone. You planned a 40-pip stop below the entry. On the MT5 app you tap Trade, tap the position, tap the pencil, and type 1.2660 in Stop Loss, then confirm. Done in under ten seconds.
At $10 per pip per lot, that stop is $400 of risk — which is why you sized the trade to one lot in the first place. The phone didn't change the plan; it just executed it.
Mobile-Specific Mistakes to Avoid
- Fat-fingering the price — a typo of one digit (1.266 vs 1.206) turns a 40-pip stop into a 640-pip one. Always re-read before confirming.
- Hitting Buy before filling Stop Loss — the most common mobile error, because the confirm button is right there.
- Weak connection mid-order — if the app reconnects, verify the stop actually attached instead of assuming it did.
- Trading on public Wi-Fi — use your data connection for order entry when it matters.
FAQ: MT5 Mobile Stop Loss
Is the mobile app the same as desktop for stop losses? Functionally yes — you can set, modify and remove stop losses the same way. The screens are just smaller.
Can I use a trailing stop from mobile? The standard mobile app has limited trailing-stop support; it's much easier on desktop. Use a fixed stop loss on mobile.
Do I need the app open for the stop to work? No — once attached, the stop loss sits on the broker's server and works even if you close the app.
Bottom Line
Setting a stop loss on MT5 mobile is identical in spirit to desktop — fill in the field before you trade, or edit the open position afterward. The phone just makes it more tempting to skip. Don't.
