Why I No Longer Chase Shorts When the Dollar Index Spikes
After ten years trading gold, I've seen countless times when the dollar index shoots up with a big bullish candle and gold immediately gets hammered. In my early years, my first reaction was to chase the short, but I often got stopped out before the real move happened. Later, I learned to check a few things first before deciding whether to act.
The most memorable case was one day last June. Right after the European session opened, the dollar index rallied from around 104.20 to 104.60 in half an hour, and gold dropped straight from 2365 to 2352. I chased a 0.5-lot short at 2358 with a stop at 2363. Price rebounded to 2364, took out my stop, and only then continued down to 2345. That trade lost $250—not much, but it made me reflect: when the dollar spikes, the first leg down in gold is often not the best entry point.
Now my approach is: when the dollar index spikes, first look at the strength and location of gold's decline. If gold is above a key support (like the previous low or the intraday pivot), I won't chase the short; instead, I wait for a pullback confirmation. Specifically, I wait for gold to rebound to around the 50% retracement of the decline and show clear selling pressure (like a bearish candle engulfing the previous bullish candle) before considering an entry. I place my stop 3-5 dollars above the rebound high and keep my position size within 0.3 lots. That way, even if I get stopped out, the loss is limited.
A Pitfall I've Fallen Into: Don't Bet on Direction Before the US Session Open
Another lesson is about timing. Dollar index spikes often happen around the US session open, especially when data is released. Once, 15 minutes before the US open, I saw dollar index futures suddenly rally and shorted 0.8 lots of gold at 2340 with a stop at 2345. After the data came out, the dollar spiked and then pulled back, and gold shot up to 2352. I got stopped out and lost $960. After that, I set a rule for myself: no new positions in the 30 minutes before the US open unless there's a very clear signal.
Now, if the dollar index spikes before the US open, I observe first and wait 15-20 minutes after the open to see if gold's reaction to the dollar persists. If the dollar pulls back but gold doesn't rise, or gold's rebound is weak, I'll consider a short. I usually place a short order around 2350 with a stop at 2355 and a target of 2335, with a 0.5-lot position. This way I might miss the first wave, but the win rate is higher.
My Current Filter Rule: Dollar Spike + Gold at Key Level + Volume
Through these lessons, I've summed up a simple filter rule that doesn't require complex indicators. When the dollar index rises more than 0.4% in 30 minutes, gold is at an intraday key level (like the previous high/low, or the Asian/European session high/low), and volume clearly expands during the decline (you can use tick volume or a simple volume bar), I'll consider shorting with the trend. Otherwise, I'd rather wait.
In practice, I enter the short when gold rebounds to 2-3 dollars below the key level, place my stop 3 dollars above the key level, and size the position at 0.3-0.5 lots. The target is the previous support level, usually 10-15 dollars. If gold doesn't rebound and breaks directly below the key level, I wait for a pullback confirmation before entering—no chasing.
Last month, the dollar index rallied from 105.00 to 105.45, gold fell from 2380 to 2368, and then consolidated around 2370. I noticed that 2370 was the previous day's support and that volume during the decline wasn't large, so I didn't act. Later, gold rebounded to 2378, and I shorted 0.3 lots with a stop at 2382 and a target of 2365. That trade made $390. Not much, but it followed my rules, and I felt at ease.
A Final Word
When trading gold during a dollar index spike, the worst thing is emotional chasing. My principle now is: better to miss than to be wrong. Before each entry, I ask myself three questions: Is gold at a key level? Is the dollar spike sustainable? Can my stop-loss and position size handle it? If any answer is uncertain, I pass. As a result, my trading frequency is lower, but my equity curve is steadier.
