Trading Strategy vs. Trading Plan.

Some people think trading strategy and trading plan are the same thing, but this is not really the case. 

Trading Strategy just tell you when to enter and exit trades while trading plan is more comprehensive and includes trading strategy. 

A trading plan may include market to trade, time frame, strategy used, entry and exit rules of strategy and money management and risk management rules.
And so we need a comprehensive plan for trading and not mere a strategy.
