Final answer:
The stop trading system is a financial market mechanism used to halt or delay trades in volatile or extraordinary situations, and it operates based on a set of rules rather than a directional 'left to right' process.
Step-by-step explanation:
The question seems to refer to a stop trading system, which is a mechanism used in financial markets to prevent trades from occurring at prices significantly away from the market price. Generally, these systems follow a set of rules applied by stock exchanges or regulatory bodies to halt or delay trades.
They are not directional in the sense of left to right; this phrasing might be a misunderstanding of trading terminologies or order execution processes.
These systems are designed to protect investors and maintain fair and orderly markets, and can be activated in cases of extreme volatility or when predefined thresholds are crossed.
The phrase "stop trading system" doesn't refer to a well-known or standardized term in finance or trading. If you're referring to a system or strategy for stopping trading activities, it would depend on the context and the specific rules or triggers set by traders or the trading platform.
Trading strategies and systems can involve various conditions, such as reaching a certain profit target, encountering a specific loss threshold, or responding to market conditions.
