Hello Japapa77 I don't straddle the PMI Manufacturing news,since this is the first high effect news for GBP this season and it is not a mark mover news,but when we get an important deviation which is -2.5 I'll trade it manually,just stick to the spike wait for retracement 20% or 30% to open your position and take profit 20 pip,if you still need to straddle used low quantity,PMI Manufacturing poll 52.8 before 52.7 deviation -2.5 (GBP/USD buy if 55.3,sell if 50.3 )take profit 20 pip.
For long term trader is very good to Long/Buy GBP/USD in 1.4550,1.4560,14570(yearly low 1.4550) because rate increase for GBP may take place in 2016. That's all for now my buddy
Thank You.
