There still might be some price change that you forget to look out that's why you were being dissapointed. If I will be trading and I don't know what will be the pros and cons, that will be absurd, not knowing it first.
Before trading first time, I must read some articles or tips here posted in these forum for a head start. Many experts are here to answer your queries about trading but not all, try to find the other answers on your own.
Well of course "trader" like you who does not know how to really trade and even does not know what trading means will always think that trading is like gambling. It will be a pain in the ass explaining that these two have different kind or risk since I think you do not know what controlled risk means. Anyway just keep on trading blindly and learn trading the hardway Keep on gambling even if you are trading.
