Shift on MA

Shift on MA - 09/12/19 21:24

I have an SMA that I shift 1 forward and it plots fine, but when I try the trade it doesn't like it.

Code

vars smaHS = series(SMA,20); \\is my series I use

when I plot:

Code

plot("SMA High",smaHS[1],0,BLUE);

it shows it on the price curve and shifted 1 bar forward,

but when I try it as a condition:

Code

 if(Close>smaHS[1])

I get an POINTER:DOUBLE:LONG error.

Do I need to specify it as a double somewhere?

Thanx

I’m assuming Close is a series?

If so, you must dereference a particular element of it, like so:

Code

if(Close[0]>smaHS[1])

In other words, you cannot compare a vars to a var. You must compare a var to a var.

Thanx AndrewAMD, makes sense yes.

Just want to ask, the numbers in [ ] specify how many bars back you want to look but with the MA I'm plotting

Code

plot("SMA High",smaHS[2],0,BLUE);

it does the shifting 2bars forward which is what I want, but when I do

Code

if(Close[1] > smaHS[2] && Close[2]<smaHS[2])

it does not look like it is taking the entries at the right place, or is the code correct for what I want to do?

Can you describe your intended entry conditions?

On the chart there is a SMA that is shifted 2bars forward. When Close[1] is above the SMA and Close[2] should still be below SMA, then a condition is met

You just regurgitated your code instead of rewriting your entry conditions in a logical paragraph form, which I would have preferred. I say this because your description is possibly wrong, and I have no way to confirm this.

Anyways, if you set Verbose = 7 | DIAG, and set(LOGFILE), add various printf statements, and then read the logs in your log folder, you will be able to troubleshoot your script.

If you're still having trouble, post your **entire** script and not little snippets.
