I havent clicked up the link but replying basing up on the sentiments that you had stated above. When it comes to technical aspect then there's no assurance that it would really be giving out that 100% precision as always. The market is really that only having two possible movements on which it would really be neither going up or down. Doesnt matter on what those TA would really be telling or showing on. Lets just always consider that there are other external factors on which it could really affect out those price movements or having nothing at all on which it do really makes even more harder to predict on where it would really be that going.
As for Big movements then even those technical indicators showing up some signs already for such big movement then better not to make yourself that get confident, everything could changed in a snap.

This is why it would really be that important that you should really be that taking up considerations on other aspects about potential movement which wont really be getting in line on what those TA's been showing.
Somehow it would really be that hard to make out some entry or exit decisions without any basis and this is why it would really be just that a normal approach that you would really be basing up everything
with those analysis on which its something recommended rather than on making decisions on random manner or having no basis because its really just that literally gambling.
