Gold is still in an uptrend. Price ran hard up, then started pulling back. The big red wick down to 4,235 was a liquidity sweep it flushed weak longs out.
That's exactly what "Expecting a buy on gold after confirmation" means. Don't jump in while it's still falling, wait for that bullish confirmation.
If 4H closes below 4,290-4,295, this W setup is cancelled. No buy.
