Copperman,
NG opened up about .35% - but that was a weak open and not as per expectations. So instinctively, I closed my long position and took some profits. One thing I have learnt is that our analysis or opinions do not matter. Charts and rules for capital preservation and taking profit does.
For NG, 143.20 was the previous day low (a level from which longs were formed) So after weak open, expected price to retrace at that level, which it did. Am long again now with a close SL of 142.70 Let's see what happens....
