Hi Chalky
A number of factors
1 -GU needed to breach under 50 by 9 21 am to try a test lower
2. We got down to 52 - but then stopped - and what was nice it was then the start of the new time window at 9 21
3. In then the case of the 3 quick white Lrs and as you say the 15 was under and for me it was worth a 3 pip stop for a trying a scalp buy
4, By 9 23 am we had more quick lrs under and price rising - so was happy it was turning to try higher
5. Also if you look at my 1 min chart - you can see the LR price structure was saying - price was finding supports and therefore might try higher
6 I was surprised on size of rise - approx over 20+ pips - I thought we would pull back under 63 -65- but then the Lrs kept me in the scalp buy - although I dropped to 30% stakes and banked 70% profits- to be safe - as scalping had been small prior to this one move
Hope that helps - if you get a few clues saying a change - it then the case of trying and if you only make 2-5 pips - take profit - but if it keep trying and quick lrs are still saying buy - stay with it
Regards
