Could use some help with a coding issue

[bsegura]

Hello:

I was hoping someone could help me with a coding issue I am having:

When a trigger occurs, I am trying to draw a continuous horizontal line from that close until the next trigger occurs - then it will again draw a horizontal line from that close until the next trigger.


I thought it would be like:

trigger := if (cross(close,ma(close,30),1,0);.....................................(produce the trigger and get a 1 or 0 result)

b := barssince(trigger);.................................................................... (find out the amount of bars since the trigger happened)

horizontal_line : ref(close,b);........................................................ (have it draw a continuous horizontal line at the close where the trigger happened until the next trigger


This is easily done in the Think or Swim platform - but I am having trouble trying to code it in this Formula Script

Thanks,
Brian

Hi Brian,

You can use VALUEWHEN(CLOSE, Trigger) to get the value of Close when the trigger is true.
Here's the full script:

Code: Select all

trigger:= IF(CROSS(CLOSE, MA(CLOSE,30)),1,0);
B: VALUEWHEN(CLOSE,trigger),colorblue,width2,pointdot;

This produces the following plot:
