Instrument Guide
GBP/JPY is one of the most volatile major crosses, making position sizing critical for survival. The 150-pip average daily range means your stops need breathing room - anything under 40 pips is asking for trouble on this beast. The $9.1 pip value per lot is higher than most USD-based pairs, so your position sizes will be smaller than you might expect.
For stop loss placement, I typically use 50-80 pips depending on the setup. On a breakout, 50 pips works. For swing trades around support/resistance, give it 70-80 pips or you'll get shaken out by normal noise.
Worked example at 1% risk: $100,000 account risking $1,000. With a 50-pip stop, that's $1,000 ÷ (50 × $9.1) = 2.2 lots. At 2% risk ($2,000), you could take 4.4 lots with the same stop.
With a 70-pip stop at 1% risk: $1,000 ÷ (70 × $9.1) = 1.57 lots. Notice how quickly your position size drops as stops widen - this is why tight risk management is crucial on Cable-Yen.
This pair suits Quant Tekel's rules well. The 4% daily loss limit gives you multiple shots (4 trades at 1% each), and the volatility means you can realistically hit that 8% profit target in a single good trade. The 10% max drawdown requires discipline - never risk more than 2% per trade to stay safely within limits. GBP/JPY rewards patient traders who size correctly and punishes those who don't respect its power.
