iPulsar - indicator of critical price levels

No permission to download
The indicator registers the price level breakout moments and the significance of these levels. The significance of a level is determined by how long it had not been broken through in the past. The level breakout may be interpreted as a possible start of the price movement reversal.

There is a noise filter and a signal significance filter, which allow to exclude reactions to insignificant levels, as well as the signals with no substantially new information.

Developed in 2012, published on the MQL4 forum. Improved on 2015 on the request of Lesorub — added alerts for parallel tracking of several price charts by the trader.

External variables:

  • Scale — the timescale of "looking into the past" (in minutes). I generally use 1440, i.e. I measure the significance of the level in 24 hours.
  • ScaleDigits — the number of digits after the decimal point on the "looking into the past" timescale (y-axis). Does not affect anything but the digitizing of the y-axis.
  • LevelFilter — the minimum significance (depth of operation) of the displayed levels. Measured in Scale periods, i.e. in my case — in natural days.
  • SignalFilter — the signal significance filter; specified either in bars (if >=0), or in Scale periods (if <0). It allows to exclude the display of the signals which contain no substantially new information relative to the one already displayed. The zero value simply disables the repeated display of the already present levels.
  • SetSignalFilter — command for activation of the SignalFilter. If false, then the signals are not filtered by significance.

Usage example:

Launching the indicator on November 27, 2015, with the significance filter disabled and with the levels of significance below 5 trade days (a trading week) omitted, gives:
