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.

Settings

There are several settings to be customized in the heatmap indicator:

Setting	Possible values	Description
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.
