MT5 Expert Advisors (EAs) — Installation & Configuration

Setup Guide.

Everything needed to take an LY Bot from purchase to a running, verified install on your MetaTrader 5 account. Six steps. You configure. The software applies.

SEC. 00 — BEFORE YOU START

What you need on the bench.

About VPS

A VPS is recommended for 24/5 operation but not required. Your EA runs whenever MT5 is open — with or without a VPS. If MT5 is closed, disconnected, or your machine is offline, the EA cannot trade.

SEC. 01 — STEP 1

Purchase.

Choose individual LY Bot EAs or the complete instrument set at bots.lytraders.com. Each EA is built for one market on one timeframe.

SEC. 02 — STEP 2

Submit your MT5 account number.

Each licence binds to one MT5 account — yours, not ours. We never have access to your funds. After purchase, you’ll be prompted to submit your MT5 account number: the number you use to log in to MetaTrader 5. Find it in the Navigator panel under Accounts, or in the Toolbox at the bottom of MT5.

We then prepare your account-bound licence key and delivery package. Expect delivery within 48 hours.

One licence · one account · one symbol

A key works on one MT5 account for one instrument. To run multiple instruments, you need one licence per instrument. Changing computers or VPS providers does not require a new key — the licence is bound to your MT5 account number, not your machine.

SEC. 03 — STEP 3 · NO LICENCE KEY NEEDED

Install & prepare MT5.

Your EA files arrive with your purchase confirmation. All of this step can be done while you wait for your key.

3.1 — OPEN THE EXPERTS FOLDER

In MT5, click File → Open Data Folder, then open MQL5 → Experts.

3.2 — COPY YOUR EA FILES

Copy the .ex5 file(s) you received by email into this folder.

3.3 — REFRESH MT5

Close and reopen MetaTrader 5, or right-click Expert Advisors in the Navigator panel and select Refresh. Your LY Bot(s) now appear under Expert Advisors.

3.4 — ENABLE AUTOMATED TRADING (ONCE)

In the top toolbar, find the Algo Trading button. If it shows red, click it — it should turn green. Then click Tools → Options and configure:

TabSetting
ServerKeep personal settings and data at startup
ChartsSelect all display options. Magnet sensitivity: 50. Max bars in chart: 50,000
Expert AdvisorsAllow algorithmic trading. Enable Allow DLL imports only if the EA prompts for it — leave it off otherwise
EventsDisable sound events (recommended)

One Click Trading (Trade tab) is optional — it is a manual-trading convenience and is not required for the EA to operate.

3.5 — ATTACH THE EA TO ITS CHART

Each LY Bot is programmed for one specific market and timeframe. Attaching to the wrong chart causes errors.

EAChart SymbolTimeframe
LY-GoldXAUUSD15-minute (M15)
LY-JP225JP22515-minute (M15)
LY-HK50HK5030-minute (M30)
  1. Drag and drop: open the correct chart, set the required timeframe, drag the EA from the Navigator panel onto the chart; or
  2. Right-click: in the Navigator panel, right-click the EA and select Attach to Chart.
Do I attach the EA to every chart?

Yes. Each LY Bot is a specialised EA — it works only on its designated market and timeframe. To run multiple instruments, attach each EA to its corresponding chart. They run independently, side by side.

SEC. 04 — STEP 4 · LICENCE KEY REQUIRED

Activate & configure your parameters.

When you attach the EA, a properties window opens. On the Common tab, ensure Allow Algo Trading is ticked. Then open the Inputs tab.

4.1 — LICENCE KEY

Enter your licence key exactly as delivered. The key activates only on the MT5 account number you submitted at purchase. If the key is invalid or the account doesn’t match, the EA will not trade.

4.2 — USER-ADJUSTABLE PARAMETERS

Each LY Bot ships pre-configured with default settings. The key settings are below; you can also adjust the emergency stop-loss. The strategy's core logic — including the trailing-stop settings — is fixed and not customer-adjustable.

ParameterWhat it doesRecommendation
Lot SizePosition size per tradeStart small. Match your account. See Sec. 06 and your Lot Size Reference.
Magic NumberIdentifies EA tradesLeave as default, or set a unique number if running multiple EAs
Session FilterRestricts the EA to its designated trading sessions, or allows continuous 24/5 operationTRUE (recommended). Set to FALSE to run 24/5.

JP2251.02501.0
HK500.12500.1
XAUUSD0.010.500.01

Maximum lot sizes shown are for IC Markets MT5 and vary by broker.

Click OK. The EA name and a status icon appear in the top-right corner of the chart — the EA is now active.

SEC. 05 — STEP 5

Test before you go live.

No blind go-live. Before the EA touches a funded account, run it where mistakes cost nothing — until you understand exactly what it does, and doesn’t.

  1. Strategy Tester: in MT5, press Ctrl+R to open the Strategy Tester. Select your EA, its designated symbol and timeframe, and run it over historical data. Watch how it behaves inside and outside its session window.
  2. Demo account: attach the EA to the matching chart on a demo account and let it run through at least a few full sessions. Confirm it opens, manages, and closes positions the way you expect.
  3. Only then attach it to your live account, starting at a small lot size.
Why we insist on this

A tool you don’t understand isn’t discipline — it’s delegation. Backtesting and demo results do not predict live results; their purpose is comprehension, not forecasting.

SEC. 06 — STEP 6

Verify & set your lot size.

6.1 — FIRST FIVE MINUTES CHECKLIST
  • EA visible in Navigator
  • Correct chart symbol and timeframe
  • Algo Trading button is green
  • EA status icon visible on the chart (top-right corner)
  • No licence errors in the Journal tab (press Ctrl+T to open the Toolbox)
  • No other error messages in the Journal tab
6.2 — SET YOUR LOT SIZE

Your lot size controls how much capital each trade deploys. Too large risks your account; too small and the position has no meaningful effect. Quick start: find your account size and broker in the Lot Size Reference document included with your delivery email, which contains pre-calculated worked examples.

If your account size isn’t in the table, the reference document uses this worksheet:

Lot Size = (Account Equity × Risk Multiplier × Allocation %) ÷ Contract Value
MarketAllocation %
HK5046.2%
JP22538.6%
XAUUSD15.3%
  • Round DOWN to your broker’s minimum lot step. Never round up.
  • Risk Multiplier: start at 1× (conservative). Use 2× only if you understand the additional risk.
  • Contract Value: broker-specific — see the Lot Size Reference document.
  • If your lot size rounds to zero: some markets (especially Gold) need a larger account to trade at a meaningful level. See “Small Account Guidance” in the Lot Size Reference.
Never copy lot sizes between brokers

The same market can carry vastly different contract sizes across brokers. Example: 1 lot of HK50 on IC Markets ≈ $3,045 of exposure; 1 lot of HK50 on CMC Markets ≈ $152,380. Always recalculate for your broker.

These worksheets describe how the software’s sizing parameters work. They are not financial advice, and no lot size guarantees any outcome. You choose your position size; you remain in control.

SEC. 07 — TROUBLESHOOTING

If something doesn’t tick.

ProblemWhat to check
EA not in NavigatorRestart MT5. Verify the .ex5 file is in MQL5/Experts/. Right-click Expert Advisors → Refresh.
“Invalid licence” errorConfirm the key was entered exactly as delivered. Check you’re logged in to the MT5 account number you submitted. Contact support if it persists.
EA not tradingIs Algo Trading green? Is the Session Filter set to TRUE and the market inside its session hours? Is the correct chart and timeframe open?
Wrong timeframe errorSwitch the chart to the correct timeframe for your EA (see the table in Step 3.5).
No trades for daysThis is often normal — the EA waits when its rules aren’t met. Check the Session Filter setting and market hours first. To confirm the filter isn’t the cause, temporarily set it to FALSE (24/5) on a demo account first.
EA status icon not showingReopen Tools → Options → Expert Advisors and confirm “Allow algorithmic trading” is ticked. Reattach the EA.
