Do you need to insert a time slot for a Tradestation or MultiCharts indicator or trading system? With StartTime and EndTime in EasyLanguage, it will be straightforward.
We create a simple indicator that draws a histogram within a given time session.
The code is straightforward:
Inputs:
StartTime(2300),
EndTime(1200);
If Time > StartTime and Time < EndTime then
Plot1(1);
End;We have received many emails because many users do not know how to solve the problem of a StartTime < EndTime.
For example, suppose we want to start a session from 22:00 to 12:00 in the next day.
In this case, our code would not work because StartTime is bigger than EndTime.
There are various ways to solve this problem; we have created this simple code:
Input:
MA_length(20);
vars:
MA(0),
color(white);
MA = average(Close, MA_length);
If MA>MA[1] and MA[1]>MA[2] then
color = Green;
If MA<MA[1] and MA[1]<MA[2] then
color = Red;
Plot1( MA, “MA”,color,0,3 );What if we wanted to use this code to open positions or for something else?
You will need to create a handy true false function.
// EasyLanguage StartTime EndTime
inputs:
StartTime(numericsimple),
EndTime(numericsimple);
If StartTime > EndTime then Begin
If (Time > StartTime and Time < 2359) or (Time >= 000 and Time < EndTime) then
BoxTime=true
Else
BoxTime=False;
End;
If StartTime < EndTime then Begin
If Time > StartTime and Time < EndTime then
BoxTime=true
Else
BoxTime=False;
End;This function can be used both for an indicator and for a strategy.
Here’s how the indicator becomes simple using the function:
// EasyLanguage StartTime EndTime
Inputs:
StartTime(2300),
EndTime(1200);
If BoxTime(StartTime,EndTime) Then
Plot1(1);With this function we can, for example, create a strategy that buys and sells at a certain time.
We can use the function both as a filter to allow us to open new positions only in a certain period.
For example, we will write:
If RSI> 90 and BoxTime = True then ……
This function allows for endless uses. Remember that creating a special function is always the optimal choice.
The code of your indicator or strategy will remain cleaner and more understandable.
