How the indicator works

This indicator only works on the 1min timeframe.
On other timeframes, only the horizontal lines remain visible.
The second indicator window is not visible on other timeframes.

The indicator uses horizontal lines to create buy or sell alerts.
These horizontal lines can be moved manually by the user from the chart.
The alerts are displayed in a second window, in the lower part of the indicator.
These alerts are displayed with yellow dots (bearish alerts) or blue dots (bullish alerts).

The indicator calculates these alerts for several different timeframes in a second window.
In this second window, each timeframe authorized to create alerts is identified by a single horizontal line.
The user himself configures the timeframes authorized to create alerts.
Bullish alerts and bearish alerts from the same timeframe are grouped on the same horizontal line.
Finally, the alert conditions make it impossible to create a bullish alert and a bearish alert under the same candle.

The main bug to fix

Indicator alerts are only given on the 1min timeframe.
The bug
Alerts are given 1 minute late.
Example
When the conditions are met at the close of the 2:11 p.m. candle, the indicator creates the alert at the close of the 2:12 p.m. candle.
This is true for alerts of all timeframes, including 1min.
-------------------------------------------------- -------------------------------------------------- ----------------

2 other things to fix
For a bullish alert, the closing price of the alert candle must be greater than the high price of the previous candle.
For a bearish alert, the closing price of the alert candle must be smaller than the lowest price of the previous candle.
I would like these 2 conditions to be removed.
-------------------------------------------------- -------------------------------------------------- ----------------

Finally, the alerts are displayed in the form of a point, yellow or blue, in the second window.
I want these alerts to be displayed in the form of an arrow, bullish or bearish, and always in yellow and blue colors.
-------------------------------------------------- -------------------------------------------------- ----------------

To note
In the second window, the last horizontal line (at the top) represents a Combo of several alerts.
This alert, and alert line, is now useless.

Very last thing
I would like to add the following 2 pieces of information to the graph.
The last known spread value when the chart is refreshed.
And the current timetable, with the seconds ticking by.
I've attached a screenshot to show you what I want.
