WRB Hidden Gap

WRB Hidden Gap MetaTrader indicator — detects and marks WRB. WRB is either a Wide Range Bar (a very long bar) or Wide Range Body (a candlestick with very long body). As WRB by themselves do not offer much information, the indicator also detects Hidden Gaps based on the WRB. It also shows filled and unfilled Hidden Gaps differently, so that it is easier to see the current market situation at a single glance. Optional alerts can be used to get signals when the current price first enters an unfilled Hidden Gap, when a new WRB or HG appears, and when a hidden gap gets filled. The indicator is available for both MT4 and MT5.

• AlertWRB (default = false) — if true, alerts will be issued when a new WRB appears.
• AlertHGFill (default = false) — if true, alerts will be issued when a Hidden Gap gets filled.

Example and strategy

The chart shows an example of Hidden Gap markup on the EUR/USD daily timeframe with default settings. The red diamonds are drawn inside WRB bars. Hidden Gaps are depicted using rectangles of various colors. Unfilled Hidden Gaps are shown with rectangles spanning past the right edge of the chart. Hidden Gap rectangles change color when an unfilled Hidden Gap of another color currently exists and intersects with a new Hidden Gap. The image shows only Wide Range Bodies (UseWholeBars = false). As you can see, there isn't much difference when switching to Wide Range Bars (UseWholeBars = true):

This indicator does not generate any trading signals. It offers information about price action to aid a trader with entry and exit signals generated by some other strategy. WRB bars are nearly meaningless, but only WRB can show a Hidden Gap. A Hidden Gap, in its turn, can be treated as a sort of pivot or support/resistance zone. Hidden Gaps can also be treated as the usual price gaps (weekly, for example).

An entry signal (by some trading system) coinciding with the price entering a Hidden Gap rectangle can be considered confirmed, while the opposite edge of the rectangle can be used as a target level. If your system generates a trade outside the Hidden Gap territory, the latter can be used either as take-profit or as stop-loss.
