The Renko (and range) functionality in the Custom Timeframe Generator has been replaced by a new Renko indicator

The Custom Timeframe Generator lets you create charts for timeframes which are not available by default in MT4:

• Periods such as M3 or H2
• Seconds-charts, e.g. 10-second charts
• Tick charts

You run a Generator EA on a normal chart for your chosen symbol, and the custom timeframe is then available from MT4's list of offline charts. The custom timeframe continues to update for as long as the Generator EA is running.

The software can create historic bars for periods such as M3 from historic M1 data, and can optionally interpolate missing bars on shorter timeframes (e.g. create empty bars on a 10-second chart if there are no ticks within a 10-second period).

Most EAs and indicators will run successfully without modification on the custom chart. (Howevever, please test EAs thoroughly before using them to trade real money from a custom chart.)
