Just wanna add something to this thread maybe it have some value maybe not but it all depends ...
Few thing need to be ask before start a trade, from my experience the 1st question to ask is what pair did i want to trade? Do we already know the character of this pair to trade the pair? If the answer is no get a clearer picture like what is the pair range movement for every TF, the pip reversal on every TF, normal extreme movement ( ex. when there is some news what is the pip range during this period ) etc etc.
Find out what is the pair busy / volatile period too and choose the best moment to trade the pair according to our trading systems.
Now we go to next question which we as a trader need to answer. After we know the average movement ask ourself does our acc margin have enough to to cover the average pip range for this pair? A simple yes or no answer will give a clear picture if we can trade the pair.
Now move on to the next question how we wanna trade this pair? There are so many trading systems which in my opinion there is no right or wrong systems just the way we trade that suit our need or acc margin or personality, but most important factor in choosing a trading system is we need to understand the systems thoroughly. (For someone who like to click a lot Swing Trading definately a no

) Even when using EA we need to understand what the ea doing, we have to control the ea not the other way around.
For manual trading we need to understand what ever factor / variable that aid us in the decision making to enter the trade. Ex. Using MACD we need to understand where the figure in setting up the MACD come from for example some ppl use 5/13 or some use standard 12/26, dont depend on luck learn where those number come from and understand it so we can control all the element in our trade. Always remember we can't control the market but we can control our trade.
Always have a workable target for daily trade / weekly / monthly. There is no magic figure. Some ppl comfortable on 2% some 5% and i have known few ppl who think they can get 100% per day ( They really believe that although their result never show that

(). There is no right or wrong with this figure it just personal preference. But the higher the number the higher the risk we have to take so think for yourself.
Always stick to your trading systems because what works for other doesn't guarantee will works for us. Always remember there is no ea or trading systems that works in every markets condition. So knowing our own ea / systems weaknesses will save our account a lot. When we know what is the weaknessess of our systems and we see the condition that can do serious damage to our acc stop the trade. Better to lose $100 than to lose $1000.
Always get out from a bad trade when we realised it is a bad trade. There is no forex god or something ( methaphor speaking ) dont pray to them to reverse our bad trade just get out of the market and start fresh.
Lastly happy pipping..
