DrawBarAnnotation-Font-Override

2021-10-13T23:23:12Z - 2021-10-13T23:23:12Z ago

While we can work around with DrawText, font control for DrawBarAnnotation would be nice to have.

Thanks... Rick

All .NET framework strings will take 16-bit Unicode characters. So if you simply substitute one of the Unicode characters for the up-arrow and down-arrow, you have what you want without changing fonts. https://unicode-table.com/en/sets/arrow-symbols/#up-arrows

CODE:
using WealthLab.Backtest;
using WealthLab.Core;
using System.Drawing;

namespace WealthScript3 
{
    public class MyStrategy : UserStrategyBase
    {
        public override void Execute(BarHistory bars, int idx)
        {
           if (idx == 0)
            return;
         if (bars.High[idx] > bars.High[idx - 1] && bars.Low[idx] < bars.Low[idx - 1])
         {
            bool isBullish = bars.Close[idx] > bars.Open[idx];
            string annotation = isBullish ? "\u21D1" : "\u21D3";
            Color c = isBullish ? Color.Green : Color.Red;
            DrawBarAnnotation(annotation, idx, isBullish, c, 20);
         }
        }
    }
}

Is there another reason you have to change fonts for DrawBarAnnotation?

We did add a "Font" optional parameter to the end of the method for Build 28:

CODE:

        //Initialize
        public override void Initialize(BarHistory bars)
        {
         DrawBarAnnotation("Above", bars.Count - 40, true, Color.Black, 12);
         DrawBarAnnotation("Below", bars.Count - 40, false, Color.Black, 12, true, new Font("Wingdings", 12));
        }
