Identical on paper, but the tight stop is more exposed to execution. A 4 pip slip on an 8 pip stop adds 50 percent to the planned loss. The same slip on a 35 pip stop adds about 11 percent. So around releases, where slippage of a few pips is normal, the 8 pip setup carries noticeably more real risk for the same nominal percentage.

Lot rounding adds a smaller distortion. With 50 dollars at risk on EURUSD, the 35 pip stop needs 0.142 lots, which rounds down to 0.14, and the 8 pip stop needs 0.625, which rounds to 0.62. Small differences, but on micro accounts they get proportionally larger.

None of that undermines the principle. Percentage risk is still the anchor. It's just worth adding a rule that tight-stop setups are skipped, or sized down, near scheduled data.

Percent bumps after clean process days beat fixed-lot doubling. Fixed lot to 2x feels fine going up and leaves you oversized on the way back down.

Size from stop distance into risk units — same language on gold and majors.

Decoupling volatility from emotion is the best argument for percentage risk. It also helps with comparing results. When every trade risks the same percentage, results in R tell the full story, and a month with wide stops can be compared directly with a month of tight ones. Traders who size in fixed pips often find their worst losses come from the wide-stop days, simply because the position was not reduced. The percentage rule fixes that automatically, as long as the stop is set first and the lot size follows from it.
