Description
New Version: 1.1
Add the calculation left room candles function, it can get the number of candles didn't touch the pinbar price
New parameters:
CustomCalLeftRoomCandle: set how many left candles needs to be calculated
CustomLeftRoomLength(%): the percentage of the pinbar nose length to be compared
Result:
This is a PinBar detector indicator and I convert from the MT4 version (not convert by auto online tool)
so you can also go to the below line for detail description:
https://www.earnforex.com/metatrader-indicators/Pinbar-Detector/
Pinbar Detector is an indicator that tries to detect Pinbars (also known as "Pin-bar" or "Pin bar") and marks them by placing a "smiling face" symbol below the bullish Pinbars and above the bearish Pinbars. It is a pure price action indicator, which is not using any standard technical indicators in its code. The configuration of Pinbar detection can be done via the indicator's input parameters. Pinbar Detector can issue platform alerts and email alerts on detection. The indicator is available both for MT4 and MT5 versions of the trading platform.
Support parameters:
Input parameters
- CountBars (default = 0) — the maximum number of bars, on which to detect the pinbars. 0 = all.
- DisplayDistance (default = 5) — the distance from the candles to the pinbar "smiling face" symbols.
- UseAlerts (default = true) — tells the indicator to issue platform alert with sound on Pinbar detection.
- UseEmailAlerts (default = false) — tells the indicator to issue an email alert on Pinbar detection. Email should be properly configured in MetaTrader via Tools->Options->Email.
- UseCustomSettings (default = false) — tells the indicator to use custom Pinbar detection parameters described below.
- CustomMaxNoseBodySize (default = 0.33) — maximum allowed body/length ratio for the Nose bar.
- CustomNoseBodyPosition (default = 0.4) — Nose body should be positioned in the top (bottom for bearish pattern) part of the Nose bar.
- CustomLeftEyeOppositeDirection (default = true) — tells the indicator that the Left Eye bar should be bearish for bullish Pinbar, and bullish for bearish Pinbar.
- CustomNoseSameDirection (default = true) — tells the indicator that the Nose bar should be of the same direction as the pattern itself.
- CustomNoseBodyInsideLeftEyeBody (default = false) — tells the indicator that the Nose body should be inside the Left Eye body.
- CustomLeftEyeMinBodySize (default = 0.1) — minimum size of the Left Eye body relative to the bar length.
- CustomNoseProtruding (default = 0.5) — minimum protrusion of the Nose bar relative to the bar length.
- CustomNoseBodyToLeftEyeBody (default = 1) — maximum size of the Nose body relative to the Left eye body.
- CustomNoseLengthToLeftEyeLength (default = 0) — minimum Nose length relative to the Left Eye length.
- CustomLeftEyeDepth (default = 0.2) — minimum depth of the Left Eye relative to its length. Depth is length of the part of the bar behind the Nose.

Hi Symposium,
Thanks for your suggestion, I have updated the indicator to show the left room candles! :)
Hi Winsonet, nice bit of coding for a very popular and successful strategy. Is there a possibility you could add a parameter (and logic) to define the amount of "room to the left" (in candles) prior to a Bullish or Bearish signal.
Most Pin Bar/Price Action strategies similar to yours define a clearance (no tail - no body) of somewhere between 4-7 candles prior to signal.... I hope this makes sense? See a link to the description below.

Very nice indicator thanks
