The Heatmap Indicator
This Heatmap indicator allows you to display a "heatmap" of all symbols selected in the Market Watch. In this version it shows the percent price change in relation to the last daily close, what can give a quick overview of the market.
This is a tool to help traders identify how strong is a currency in relation to all other pairs. This is a visual tool, and cannot be used inside Expert Advisors. In this sense, it's more a tool for discretionary traders, instead of automated traders. So, for those interested in using this tool for automated trading, unfortunately this is not possible.
It's particularly useful for Stocks or Futures markets, like for example Bovespa the Brazilian Exchange.
There are several settings to be customized in the heatmap indicator:
|Hide chart ?||True/False
||You can completely hide the chart or keep it as is. Chart will be restored when indicator is removed from chart.
|Chart drawn in foreground ?||True/False
||If previous setting is True, you can choose to display the chart in foreground (true) or background (false).
|Auto arrrange heatmap ?||True/False
||If true, all sizing and arrangements are done automatically. Otherwise further settings must be selected.
|Refresh time (milliseconds)||>=1000
||Data is refreshed every 5 seconds by default. Minimum value is 1,000 (1 second).
|Up Color||any Color
