Hehe...
That one is NOT the only conclusion leh...
Still the rule of thumb is you trade your best way and not what and how others trade.
I just gave you an example that I am a picky trader.
It works for me but it might not work for you.

Use the chart to decide on the point of entry and exit but must also look at the fundamental of the stock...right?
--> If you are a sole chart trader and trade short, err.. 10 mins, 1 hour etc.. then sometimes fundamental of the stock can be bypassed.
It really depends but I like to trade with fundamentals behind the stock.
I try to avoid risky stocks, stocks with poor fundamentals, like every year lose money etc etc...
How about mother share and warrants?Look at mother's chart to decide on warrant or base it on warrant chart?
For me, I have to like the mother share fundamental.
And then depending on the conversion rate, the expiry date, I then decide if I want to load up some warrants.
I always buy warrant on the fundamentals of the mother.
If the stock is high dividend i would not consider the warrant. I will take the mother instead.
If the warrant pass the black-scholes calculation, and if leverage is greater than 2 then i will opt for the warrant instead of the mother.
