QFL single TF with alerts

Backtesting compatible QFL pine script w/alerts

This version of QFL was made based on this one:

I made the following additions according to my requirements:
- I need to use pine script 4
- I needed to avoid repainting issues so I'm not calling directly security, I'm using the wrapper function.
- There might be still repainting issues when you use "max base age" which uses the function "barssince" so be careful, you can disable it by setting its value to zero.
- Alerts so I can use it for automated trading and bots
- In order to make this signal compatible with the backtest script there's an option provided in the settings. If you enable this option this indicator will plot 1 whenever there's a BUY signal. This will allow the backtest to pick the "QFL Buy" from external indicator so it can perform the backtest.

I recommend some of these settings to start playing with the chart in 15 min / QFL in 1, 2 or 4 hours.
The higher the TF the more conservative.
QFL with 3.5% is pretty popular but you can try higher QFL percentage settings for a more conservative approach.

Notas de prensa:

- added sell signal
- added toggle to hide bases and buy/sell signals
- added alerts

Notas de prensa:

- added separated sell percentage parameter. Example of use: you can buy at 3.5% and sell at 2% which could make more sense on a bear market.

Notas de prensa:

- changed default max candle age to disabled
- added an option to allow consecutive signals which triggers signals that match the condition in two or more consecutive candles. This can help to place multiple trades when they manage to close quick enough.
- added an option for allowing signals that are consecutive when the base has changed even if the allow consecutive signals option is turned off

Notas de prensa:

Support for knowing when the base has moved to a new price.
Base change works for longs and shorts.
It supports alerts and it shows a label when the base changes.
Remember that QFL bases are plotted with an offset of 3 candles according to the original design, so the label and the alert will only be trigger once the base 100% confirmed to prevent re painting but this will mean the label will look shifted to the right.
