Heikin Ashi EFS question

[earlinarizona]

1) How do you make candle for this EFS larger?. Changed every number in the EFS to see and no go and hit thicker lines in E Signal and nothing. The candles that come with this EFS are just too small.

2) It looks like the candle color is being drawn 1 bar too late. I put setPlotType(PLOTTYPE_INSTANTCOLORLINE); to get it to back up but it did not work. Normally I place this in every one of my EFS files and it does work. Does something need to be changed. If the color changed one bar earlier that would work give a better entry.


Thanks

Hello Earl,

1. The thickness of the candles is controlled by the drawLineRelative() functions. Change the thickness parameter, 3, in the following line. The lines were kept fairly thin because thicker lines drawn with this function show the rounded ends of the line more, which was undesirable for this study.

drawLineRelative(0, haOpen, 0, haClose, PS_SOLID, 3, vColor, "Body"+iCntr);

2. I'm not sure what you're trying to accomplish with the coloring here. The color of the candle is based on the close relative to the open for the candle. If the close of the heikin-ashi bar is above it's open the color will be green. Red if below, similar to regular candles.
