Top Bottom EA — EURUSD Volatility Adaptive EA, 3.38 Profit Factor Over 10 Years

Top Bottom EA is a MetaTrader 4 expert advisor that trades EURUSD and GBPCAD using a volatility adaptive mechanism — one position at a time, each with a hard stop loss, averaging roughly 4 trades per day held for approximately 12 hours.

A 10-year backtest on EURUSD starting from $2,000 returned a 3.38 profit factor with 81.41% win rate and 1.37% maximal drawdown. A live account on ICMarkets SC Live08 at 1:500 leverage shows 85% win rate across 208 trades.

Key Benefits

• ✅ Capital Floor: Verified to run on $20 minimum deposit across 10-year backtests — micro-account accessible, but lower capital compresses the recovery buffer on a 5-loss streak.
• ✅ Strategy: Volatility adaptive entry fires one signal at a time with every position carrying a defined stop loss — consistent exposure per trade, no position pyramiding. Compare EA strategies
• ✅ Risk Control: StopLoss fixed at 800 points and one-trade-at-a-time logic prevent simultaneous open exposure from compounding — no Martingale grid scaling. Browse more low-drawdown EAs
• ✅ Instrument Scope: Documented across EURUSD and GBPCAD with consistent profit factor above 2.18 on both pairs — multi-pair deployment is possible but each pair runs its own independent signal queue.

The primary 10-year backtest on EURUSD ($2,000 starting capital, spread 30) produced 5,824 total trades, 81.41% win rate, 3.38 profit factor, and 1.37% maximal drawdown.

The GBPCAD 10-year backtest on $20 starting capital delivered a 2.18 profit factor, 72.88% win rate, and 5.40% maximal drawdown across 6,869 trades. The EURSGD $20 backtest matched the EURUSD profit factor at 3.38 with 81.46% win rate and 1.37% maximal drawdown over 7,524 trades.

The strategy’s structural risk point is the stop loss at 800 points (StopLoss parameter). On pairs with wide spread spikes — common during major news events — the effective exit price can diverge significantly from the configured level, turning a contained loss into a larger one. This is a partial weakness: spread spikes cannot be eliminated, but scheduling the EA off during scheduled high-impact news events (NFP, FOMC) reduces the exposure window.

The maximum consecutive loss run across all backtests reached 5 trades (EURUSD and EURSGD) and 7 trades (GBPCAD). At minimum $20 deposit, 7 consecutive losses at GBPCAD’s largest loss trade of $6.41 each would consume the majority of the account — the $20 floor is a technical minimum, not a recommended operating level.

The live account data covers 208 trades from 2019 — recent spread behavior, execution latency, and current broker conditions are not reflected in that record.

How Top Bottom EA Works

Mechanism: The EA detects volatility expansion on EURUSD, GBPCAD, and EURSGD and enters in the direction of the emerging move. The Volatility parameter (default 110) sets the sensitivity threshold — higher values require stronger momentum before entry. One position opens at a time, held approximately 12 hours, which prevents multiple simultaneous open trades from compounding exposure during volatile sessions.

Signal Trigger: Entry fires when the volatility reading crosses the configured threshold. The PointDifferenceLimit (50.0) acts as a spread filter — if current spread exceeds this value, the EA skips the signal. This prevents entries during abnormally wide spread conditions.

Position Close: Each trade carries a fixed Take Profit of 300 points and a Stop Loss of 800 points. No trailing stop or basket close logic — each trade closes independently at its TP or SL level.

Exposure Limits: One trade at a time is the primary exposure control. The 800-point stop loss defines the maximum loss per trade. CompoundInterest is set to false by default — lot size stays fixed at 0.1 rather than scaling with account growth.

✅ Optimal conditions: Trending sessions with directional momentum on EURUSD or GBPCAD; stable spread environments where the PointDifferenceLimit filter functions as designed.

⚠️ Avoid when: High-impact news events that cause sudden spread spikes beyond 50 points — the filter may not block entry fast enough if the spike occurs mid-candle; choppy, range-bound markets where volatility readings trigger entries without follow-through.

Who Should Use Top Bottom EA

Purchase this EA if you:
