i haven't used OCO code, but i'm guessing it is similar to a scan code.

i think tos expects the code to have a true or false plot value, not a number.

problems,

..you are trying to use a study to determine a true/false situation, but don't have any true/false outputs (plots)

..this study is set up to be an upper chart study.

..has 4 plots. there should be just 1 plot

..all the plots have number values, not true/false (not 0 or 1)

fix

..disable all outputs , plots, AssignPriceColor() , labels, bubbles, ...

..change all the plots to def. then create 1 plot formula that will be true or false

..figure out what condition you want this oco thing to trigger on and make a new plot formula for it.

--------------------------

i made a lower chart study for you to experiment with.

it plots a spike at 1 when plot z is true, when concavity is different from the previous bar.

..i copied a formula and replaced data with 1 and double.nan with 0.

..(true is the same as 1, false is 0)

plot z = if concavity[1] != concavity then 1 else 0;
