Most Forex traders are familiar with Candlestick Charts. Candlestick charts are invented by Japanese rice traders in the 16th centuries. Over the centuries these charts have been perfected into an art form. But how about another Japanese invention, the Renko Charts? Yes, Renko Charts are another Japanese creation that has been widely used in Forex trading yet, many Forex traders might never heard of these charts. These charts are based on price only not on time. On a regular candlestick chart or a bar chart after a fixed time interval, you will find a new candlestick or a bar but not on the Renko Chart.
