SwingHighLow

Hello. Excellent indicator. I would like to be able to print in the Registry of my Cbot the maximum and minimum values ​​that they calculate. I can't do it. Please help?

Hola. Excelente indicador. Me gustaría poder imprimir en el Registro de mi Cbot los valores máximos y mínimos que calculan. No logro hacerlo. ¿Ayuda por favor?

The above has a couple corrections to the one EARL posted. It works.

But it could be cleaned up a bit and updated to newer API.

also, both high and low show in pink because red and green dont show well with my chart colors. You have to change colurs in the code with whatever color you prefer.

Maybe someone else want to modify that so color con be selected in settings.  The current selection for color in setting does not work.

But at least now it shows both highs and lows correctly

"hi

the low part is not working" 

Read the description 

"eu gostaria de saber como que coloca esse indicador com a posição de compra pois ele só marca como venda"

Leia a descricao companheiro

"The indicator of SwingHigh, please select the High source.
The indicator of SwingLow, please select the Low sources."

The programmer writes a really nice indicator and the user here is so lazy that can't even read the description.

Hi, st0424,

I have been looking for this kind of indicator and am very happy to find it.

Can you kindly advise me how to modify the code in order to change the font type and size, I will like to make it "arial" and size in 6.

Thank you very much.
