GBPUSD is oversold on the RSI, but I'm hesitant to buy. Volume isn't confirming the move down; it's actually decreasing. Could be a sign that sellers are losing steam, or just a lack of interest. Need to see some bullish volume to confirm a reversal.
Oh and should add, watch out for the smart money sweeping the lows before any major move up. They like to shake out retail traders before the real trend begins. It's a common pattern. Might wait for a clear break above yesterday's high before entering long. That's just me tho.
