These charts are the most basic type of chart and in most cases they are generally used for spread trading and longer term analysis. They are also helpful in situations when only the closing data is available, or markets where high and low price information is not measured accurately. Most charting analysis works well with this kind of chart although momentum indicators which use intra-day price high and lows don’t work particularly well with this type of chart. These type of charts also don’t plot price gap’s in the market well either.
