Trade without stubbornly sticking to one model; it's hard to make money.
Trading should be stable and profitable; don't try to do every model, focus on one trading model.
No need for obscure theories or advanced techniques.
Don't challenge yourself with high difficulty; just do simple trading.
Truly research and understand one trading model, and only trade within that model.
Then continuously practice, perfecting simple techniques, and profit will be within reach.
