Trading is a business, so you have to treat it as such if you want to succeed. Reading a few books, buying a charting program, opening a brokerage account, and starting to trade with real money is not a business plan—it is more like a recipe for disaster.
A plan should be written—with clear signals that are not subject to change—while you are trading, but subject to reevaluation when the markets are closed. The plan can change with market conditions and might see adjustments as the trader’s skill level improves. Each trader should write their own plan, taking into account personal trading styles and goals. Using someone else’s plan does not reflect your trading characteristics.
