It looks like correction has begun for GBP/USD. The pair formed a doji candlestick in the 4 hour filter chart, another in the daily filter chart, an inverted hammer in the weekly filter chart and if one takes a look at the monthly filter chart they will notice that the pair has reached a multi-year level of support at 1.5000 and I really doubt it will be able to break below it so easily.All these are very serious signs that correction is about to start, or perhaps even that the trend is about to reverse. Either way, I think this is a good place to start buying again.
