Aklamavo ICT KillZones

The indicator allows full customization of each killzone segment:

General

• DaysToDisplay : number of past days to draw killzones for.

Asian Killzone Parameters

• AsianStartHour , AsianEndHour

• AsianColor , AsianWidth

London Killzone Parameters

• LondonStartHour , LondonEndHour

• LondonColor , LondonWidth

New York Killzone Parameters

• NYStartHour , NYEndHour

• NYColor , NYWidth

These inputs determine:

• Where vertical lines are positioned.

• Their color coding.

• Their thickness on the chart.

2.1 GetSessionTime()

This function converts a date at midnight into a precise timestamp for a given session hour.

Steps:

1. Convert the day’s datetime to an MqlDateTime struct.

2. Replace hour/minute/seconds with the session parameters.

3. Convert back to a datetime.

This is how session start/end timestamps are computed reliably.

2.2 DrawLine()

Creates or updates a vertical line object on the chart.

• Uses ObjectCreate() only if the object does not already exist.

• Sets:

  • Color ( OBJPROP_COLOR )

  • Style ( STYLE_SOLID )

  • Width ( OBJPROP_WIDTH )

  • Background and Ray properties (disabled).

The line is always redrawn at the given timestamp.

3.1 DrawKillzonesForDay()

This function draws six vertical lines per day:

It uses:

• GetSessionTime() → computes timestamps

• DrawLine() → draws each vertical line

• Unique object names → include the day index i

Example:

• KZ_Asian_Start_0

• KZ_London_End_2

• KZ_NY_Start_4

This ensures no name collisions.

Actions performed:

1. Deletes all existing vertical line objects to avoid duplicates.

2. Determines today's midnight timestamp.

3. Loops DaysToDisplay times:

   • For each previous day, calculates day_start = today_start - i*86400 .

   • Calls DrawKillzonesForDay(day_start, i) .

Finally, ChartRedraw() is called to refresh the drawing immediately.

The indicator does not need to compute anything per tick or per candle, because all work is done in OnInit() . Therefore:

This makes the indicator very lightweight and CPU-efficient.
