Hi... sorry I put my foot in this thread unknowingly....
I am a pro in software ..but a novice in trading .. I am putting what I understand... If it does not makes sense .. please ignore.
What is a system:
A system is a predefined process which can be executed without the need of decision making on the fly.
Hence once designed can be given to other people who can just routinely execute it, without getting blamed for the losses..
Lets take two environmental condition trending and non-trending. (there might be other conditions also)
In trending market Saint's system will work wonders.
But for non-trending markets, we need another system (I am still searching for one, though I think Asishda's method will work here.... ).
Here we need a decision making layer which can decide, which system to use based on reading patterns/signals.
Example : few days back Saint said, avoid suzlon.. Now here he is himself the decision making layer. Saint is looking at the charts and deciding if the system will work or not.
I was suggesting, another layer which will keep on looking at charts and gives a go ahead to use the trending or non-trending system.
