GDS Renko Canvas + Donchian is a compact educational indicator for MetaTrader 5. It renders classic fixed-size Renko bricks on a single CCanvas bitmap layer and overlays a Donchian Channel calculated directly from completed Renko bricks. The horizontal axis represents Renko sequence rather than time. The internal builder uses incoming BID ticks and the classic two-brick reversal rule. The Donchian Channel is causal: for each newly completed brick, the channel is calculated from the previous N completed Renko bricks only. The current brick is excluded from its own channel calculation.

GDS Renko Brick Statistics is a compact educational indicator for MetaTrader 5 that builds classic fixed-size Renko internally from BID ticks and summarizes the behavior of the most recent completed Renko bricks.

A compact educational indicator for MetaTrader 5 that renders classic fixed-size Renko bricks on a single CCanvas bitmap layer and overlays Bollinger Bands calculated directly from completed Renko closes. The horizontal axis represents Renko sequence rather than time. The internal Renko builder uses incoming BID ticks and the classic two-brick reversal rule. Bollinger Bands are calculated only from completed Renko bricks; the forming brick is never used in the band calculation.

GDS Renko Bollinger 4-Mode Demo EA is a free educational Expert Advisor for MetaTrader 5. It demonstrates four different ways to combine classic fixed-size Renko bricks with Bollinger Bands inside one standalone EA. The EA builds four independent internal Renko streams from incoming BID ticks. Each mode has its own Renko brick size and its own Bollinger settings. Signals are generated only when a Renko brick is fully completed. Bollinger Bands are calculated causally from previous completed Renko closes, so the current brick is excluded until after its signal check.

A small educational Expert Advisor showing how Wilder's ADX and Directional Movement can be calculated directly from completed classic Renko bricks. The EA builds fixed-size Renko internally from BID ticks. No offline charts, custom symbols, DLLs or external indicators are required. +DI, -DI and ADX are updated only after a Renko brick has been completed.
