Accepted answer

highstock has point markers disabled by default. you will need to enable them explicitly as follows:

plotoptions: {
    series: {
        marker: {
            enabled: true    
        }
    }
},

if you look to your demo you'll see that using color it sets the tooltip color and not the marker.

to fix it use marker fillcolor instead, like the following.

data: [
    {x: 1343862840000, y: 4, marker:{ fillcolor: 'red'} },
    {x:1343863200000, y:5, marker:{ fillcolor: 'green'}}
]

update:
it works on highstock see this demo.
you have to init it using the right object.
use chart instead of stockchart.
