This is probably a silly question and I should be able to figure it out but I can't!
Why is it that some candles are filled in and some are clear on charts? Look at the chart below.
When I look at the candle for the 18th which is clear, the open was .027, the low was .026 and the high and close was .029
I guess that means it opened at one price, went down a little and then closed up for the day.
If you look at the candle from the 15th it is filled in. That day the it opened at .03, the high was .03, the low was .022 and it closed at .025
I think maybe by typing this I am seeing it clearer. On the 15th it closed up from the previous day but down from the open? On the 18th it closed up from the previous day AND up from the open. Is that it?
