TimeBlock

TimeBlock marks blocks of time and specific times of day, for use in BloodHound’s Threshold solver.

Use it with the Threshold solver to pick out any of its outputs. For example:

• A block of time, for an exit signal that flattens any open position before the market closes.
• A specific time, to reset a Function node that’s blocking signals so signals can resume.
• Trading holidays, to keep a system from trading on them.

It also gets around a limitation of the Time Session solver. NinjaTrader doesn’t transfer custom session templates to other computers, so a BloodHound template that uses Time Session with a custom session template only works on another computer if that session template is recreated there. TimeBlock in a Threshold solver doesn’t have that problem.

Properties

Setting	What it does
Start Time	The start of the block of time.
End Time	The end of the block of time.
Use on Monday … Sunday	Which days of the week the block applies to.
Show Text	Writes the outputs’ current values on the chart (see the image below).
Text Color	The color of that text.
Text Location	Where on the chart the text goes.
Color chart background	Colors the chart background with the three colors below.
Before Start Time Color	From midnight to the Start Time (yellow in the image above). With the default times, usually pre-market hours.
Between Start & End Time Color	From the Start Time to the End Time (dark in the image above). With the default times, usually trading hours.
After End Time Color	From the End Time to midnight (purple in the image above). With the default times, usually after-hours.

Outputs for BloodHound

Each output is true or false (a BoolSeries): 1 for true, 0 for false. In a Threshold solver, a rule like “equals 1” produces a signal on the bars where the output is true.

Output	True (1) on
IsStartBar	The bar at the Start Time.
IsEndBar	The bar at the End Time.
BeforeStartTime	Every bar from midnight up to, but not including, the Start Time bar.
BetweenTimes	Every bar from the Start Time to the End Time.
AfterEnd	Every bar after the End Time bar, up to midnight.
FirstBarOfDay	The first bar after midnight. Useful for resetting Function nodes at the start of each day.
IsTradingHoliday	Bars on a holiday or partial holiday, according to the instrument’s Trading Hours template.

Blocking signals on holidays

To stop a system trading on holidays, let signals through only on non-holiday bars:

1. Add a Threshold solver that outputs 1 when IsTradingHoliday equals 0 (not a holiday).
2. Connect it to the last AND node in your logic. On holidays it outputs 0, so the AND node blocks the signal.
