GBP/USD is still supported by the 1.2250 and it's expected to remain within that tone across the board, at least during the last week of the year. The resistance zone of 1.2317 will play a key role ahead of January, as it could bring some barrier to the bulls in the first week of trading on 2017. If a breakout happens over there, it can cling to test the 1.2390 area.
H1 chart's resistance levels: 1.2318 / 1.2390
H1 chart's support levels: 1.2249 / 1.2185
Trading recommendations for today: Based on the H1 chart, sell (short) orders only if the GBP/USD pair breaks a bearish candlestick; the support level is at 1.2249, take profit is at 1.2185 and stop loss is at 1.2312.
