EA1 — Simple Moving Average 12/26 Crossover Bot

Timeframe: M15 (15-Minute)
Strategy: SMA 12 / SMA 26 Crossover
Platform: MetaTrader 5 (MQL5)

---

Indicator Setup

Two Simple Moving Averages (SMA) are applied to the closing price of each 15-minute candle:

Line	Period	Role
Fast SMA	12	Short-term momentum
Slow SMA	26	Long-term trend direction

When the two lines cross each other, a trade signal is generated.

---

Trade Entry Logic

Signals are confirmed only on fully closed M15 bars (no repainting).
The EA compares the last two closed bars to detect a fresh crossover.

🟢 BUY Signal

Condition: SMA 12 crosses above SMA 26

Bar [2]:  SMA12  <=  SMA26   (fast was below or equal to slow)
Bar [1]:  SMA12  >   SMA26   (fast is now above slow)

Action:

1. Close any open SELL position immediately.
2. Open a BUY market order at the current Ask price.
3. Attach Stop Loss and Take Profit to the order (see below).

🔴 SELL Signal

Condition: SMA 12 crosses below SMA 26

Bar [2]:  SMA12  >=  SMA26   (fast was above or equal to slow)
Bar [1]:  SMA12  <   SMA26   (fast is now below slow)

Action:

1. Close any open BUY position immediately.
2. Open a SELL market order at the current Bid price.
3. Attach Stop Loss and Take Profit to the order (see below).

Stop Loss & Take Profit

Every trade is opened with a fixed pip-based Stop Loss and Take Profit calculated from the entry price.

Level	Pips	Direction	Purpose
Take Profit	1000 pips	In trade direction	Lock in profit when price moves favourably
Stop Loss	500 pips	Against trade direction	Limit loss if price moves the wrong way

BUY Trade Levels

Entry  =  Ask price

Take Profit  =  Ask  +  1000 pips   (price rises 1000 pips → trade closes in profit)
Stop Loss    =  Ask  -   500 pips   (price drops  500 pips → trade closes at a loss)

SELL Trade Levels

Entry  =  Bid price

Take Profit  =  Bid  -  1000 pips   (price drops 1000 pips → trade closes in profit)
Stop Loss    =  Bid  +   500 pips   (price rises  500 pips → trade closes at a loss)

---

Trade Exit Logic

A trade is closed under one of three conditions:

Condition	Type	Triggered By
Price hits Take Profit level	Profit exit	Broker / MT5 automatically
Price hits Stop Loss level	Loss exit	Broker / MT5 automatically
Opposite crossover signal fires	Signal exit	EA closes trade before opening new one

Notes

• One trade at a time — the EA never opens a second trade in the same direction.
• New bar logic — signals are only evaluated once per new M15 candle to prevent noise.
• JPY pairs — change PipSize to 0.01 when trading symbols like USDJPY or EURJPY.
• Always backtest in MetaTrader 5 Strategy Tester before running on a live account.
