everything can be explained through chart analysis, if you can read charts then you don't need to worry about trading in futures,
and if you have $ 100k of course that's a lot of money and you can lose your money easily if you can't read charts,
my advice is put stop lose -5% and use capital less than 10% when open positions, the last do not be greedy
you have point there mate..to be exact knowledge is the most important when it comes to this way of making profits. And the first thing you need to know is how to read the chart in order for you to have a clue where will be the next direction of the growth rate.. Actually someone says that no one can really predict the real movement of the chart but i don't believe on that kind of view because it all depends on you if you really interested to such things.. In fact in trading we have some useful indicators wherein that can really show us some specific information, if you are not confident about the results after using one tools then combine those indicators just to obtain the best results that can prove you the real potential of the candles.. Efforts is required but yes it will be worth it after all.
