Think of losing before buying

So far, i just trade one counter for 2015 and make some profit. First, i want to wait till the resistance level but as  usual i can't wait for profit. I have sold that stock. So winning vs losses trade 1 - 0.

Today i have been bought 2 counter. All in O&G related counter. I will wait and see. I don't know either i make the right decision to buy these 2 counter. The first counter already up about 28% and another counter down 15% from highest level this month. Technically, oil price is stable right now with little upward bias. I will reveal these 2 stock after i have sold all.
