Gj currently is slightly above the support level of 142.789, (the gold line)
In the past, we can see this price level plays pretty good for trend decisions.
As long as the price stay above this level 142.789. It should go higher to 144.036, (purple line above)
once breaks it, we can expect it goes higher to the next one, 145.437.
However, if the price can not stand above the gold line, then it will drop to last low, 141.582.
Since it's December, market could be choppy, plus the Brexit deal issues that GBP is having. Just be careful.
Last thing,
never go against the market and have good risk management. :)
We all learned it from the hardest way.
