Forums say "never trade Mondays." Some say "Fridays are the best." What does the data say? We filtered 500+ trades per weekday across all 9 forex pairs on FXAbsolute, running the same trend-following strategy. Here is every weekday, ranked by actual profit factor.
| Rank | Day | Avg Trades | Win Rate | Profit Factor | Verdict |
|---|---|---|---|---|---|
| 1 | Tuesday | 378 | 43% | 1.48 | Best |
| 2 | Wednesday | 391 | 41% | 1.39 | Strong |
| 3 | Thursday | 384 | 38% | 1.22 | Decent |
| 4 | Monday | 342 | 34% | 1.04 | Breakeven |
| 5 | Friday | 356 | 29% | 0.87 | Worst |
Tuesday ranked #1 across every forex pair tested, posting a 1.48 profit factor. Why? The market has absorbed Monday's positioning chaos, the week's trend direction is clear, and volume is at its weekly peak. Tuesday is not the "sexy" day — traders obsess over NFP Fridays and Monday gaps — but the data says it is the most profitable day of the week by a clear margin.

The conventional wisdom says Friday afternoons are quiet — but the data shows Friday as a whole is a losing proposition for trend-following strategies. Positions reverse, stops get hunted, and the late-day liquidity drain creates unpredictable behavior. The forum advice is wrong. The data is right.
| Pair | Best Day | PF | Worst Day | PF |
|---|---|---|---|---|
| GBPJPY | Tuesday | 1.72 | Friday | 0.78 |
| GBPUSD | Wednesday | 1.44 | Monday | 0.82 |
| EURUSD | Tuesday | 1.32 | Friday | 0.74 |
| USDJPY | Thursday | 1.28 | Monday | 0.85 |
The patterns vary by pair — GBPUSD peaks Wednesday, USDJPY peaks Thursday — but one rule holds universally: every pair has at least one losing day. If you can identify yours (free, on FXAbsolute), you can simply stop trading that day and improve your overall profit factor by 15-25% without changing anything else about your strategy.
