AlgowayMT5 — User Guide for MetaTrader 5 Error 4756

Error 4756 in MT5 means your order was rejected before reaching the market. The EA attempted to send a trade, but MT5 refused it due to order parameters or trading permissions.

🔍 Common Causes

• Stop Loss / Take Profit too close to the current price
• Wrong execution mode for your broker
• Lot size not valid
• Symbol name not matching broker’s
• Market closed or trading not enabled

⚙️ Prepare Your MT5 for Trading

1. Check all three Algo Trading switches in MT5:
   • Global Algo Trading button — must be green.
   • Terminal settings: Tools → Options → Expert Advisors
     • ✅ Allow algorithmic trading
     • ✅ Allow WebRequest for https://algoway.co
   • EA settings on the chart (F7 → Common tab) — ✅ Allow Algo Trading
2. Ensure the symbol matches the broker’s exact name (including suffixes like .a, .pro).
3. Market must be open, prices moving, spread reasonable, and enough free margin available.

🛠 Quick Fixes for Common 4756 Causes

1. Stop Loss / Take Profit too close — Try without SL/TP, then modify later. Or set them 2–3× further away.
2. Points vs Pips confusion — In v1.65, SL/TP are in points. On a 5-digit symbol, 1 pip = 10 points.
   • Use sl_price / tp_price for exact prices
   • Or multiply pip values by 10
3. Wrong execution mode — Change Order Filling Type: AUTO → IOC → FOK.
4. Lot size not valid — Start with smallest allowed lot (e.g., 0.01) and adjust to valid step.
5. High spread / slippage — Avoid low-liquidity hours or news releases. Test with market order without SL/TP.

🧭 Step-by-Step Diagnostic Path

1. Test without SL/TP — if works, issue is stop distance.
2. Check symbol name — match exactly in Market Watch.
3. Try smallest lot — if works, adjust to nearest allowed.
4. Switch execution mode — try IOC/FOK.
5. Retry in calm market conditions.
