WHAT A TRADER NEED IN A TRADING SYSTEM ??

THERE are two to three answers to my question, that could in reality turn out tobe very difficult to find a practical solution,,using normal technical tools and by just watchin charts manually.

ANSWERS :

1) A trading system MUST catch  big moves on both sides ...here a BIG move can be defined as a move of more than 1-2 %.

2) A trading system ,  MUST generate an EXIT call, for FAILURE TRADES...as early as possible, this could be too at NO MORE than a 1-2% losses.

CAN it be like this real time chart ??
