You are a professional PineScript version=5 developer.
You know how to code indicators and strategies and you also know their differences in code.
I need your help to turn a TradingView indicator into a strategy please.

Respect these instructions:
- Convert all Indicator specific code to Strategy specific code. Don't use any code that a TradingView Strategy won't support. Especially timeframes and gaps. Define those in code so they are semantically the same as before.

- Preserve the timeframe logic if there is one. Fill gaps.

- If the indicator is plotting something, the strategy code shall plot the same thing as well so the visuals are preserved.

- Don't trigger a short. Simply go Long and Flat.

- Always use 5% of capital.

- Set commission to 0.1%.

- Set slippage to 3.

- strategy.commission.percent and strategy.slippage don't exist in PineScript. Please avoid this mistake. Set those variables in the strategy() function when initiating the strategy.

- When initiating the strategy() function, don't use line breaks as this will cause a compiler error.

- Leave all other strategy settings to default values (aka. don't set them at all).

- Add Start Date and End Date inputs/filters so the user can choose from when to when to execute trades. Start with 1st January 2020 and go to 31st December 2050.

- When setting the title of the strategy, add "Demo GPT - " at the start of the name and then continue with the name of the strategy.


This is the code of the Indicator you shall migrate to a TradingView Strategy:




//@version=5
//The Average Daily Range is a simple concept, calculated as the difference between daily highs and lows averaged over some period.
//This indicator uses that range in conjunction with Fibonacci ratios to create zones centered on the day's open that tends to act as areas of support and resistance.
//
//A simpler version of this concept can be seen in my other script, Average Daily Range Zones,
//which does not include the Fibonacci ratio zones.
//
//Thanks to @Hank Hill for the original idea and ToS script this is based on, and
//TV for the feedback and support on the use of the security() function.
//Also thanks to @GoldenCross for the Fibonacci obsession.

//For future reference; an sma() on a security return is not the same as a security() with an sma argument.
// i.e., security(tickerid, 'D', sma(dayRange, length)) != sma(security(tickerid, 'D', dayRange), length)

//Includes TradingView's own f_security function for better historical data.
