[RJo 10]

A custom Semi-Log Scale Oscillator indicator is now available for MT5 on Metaquotes website and directly in the MT5 platform.

This indicator is an anchored semi-logarithmic scale oscillator. A logarithmic scale is widely used by professional data scientists to more accurately map information collected throughout a timeframe, in the same way that MT5 maps out price data. In fact, the underlying logic of this indicator was freely obtained from an overseas biotech scientist.

A log-log chart displays logarithmic values on both the x (horizontal) and y (vertical) axes, which generally produces a straight line that points up, down, or remains flat. A straight line is not very useful for trading markets because such a straight line is so smoothed that actual price values that appear over time are very far away from the line study. In contrast, a semi-log chart is only logged on one axis--generally, the y axis. Such a semi-log chart is well suited for trading markets because the time (x) axis is preserved in its original form while at the same time, providing a graduated y scale where the distance between price increments progressively increases as price rises higher (and decreases as price falls lower). This allows us to establish a zero level for a low price, clearly view trends on straighter angles, and clearly observe amplified price spikes at high prices. Accordingly, this indicator employs a semi-log scale on the y axis only.

This indicator is anchored because it allows you to specify a start time for calculation of price bars. The settings are as follows:

• Year.Month.Day Hour:Minute - defaults to 1970.01.01 00:01 - if left on default setting, the indicator automatically detects the earliest price bar in chart history--even where the year 1970 is not in history. Notes appear in the indicator settings window.

• Size of first pip step to log - defaults to 135 - this default is suitable for higher timeframes such a MN1 (monthly), while 5 is suitable for lower timeframes such as M1 (minute). Ultimately, optimal settings will depend on the timeframe that you attach the indicator to, the level of price volatility within that timeframe, and start time that you choose. Remember... The semi-log formula calculates from low to high, so your start time must always be a major swing low. Again, notes appear in the indicator settings window.

The standard (built-in) MT5 indicators that can be applied to the "Previous indicator's data" can be applied to this indicator.

Indicator lines (indicator buffers) can be called with iCustom in Expert Advisors created by Expert Advisor builder software or custom coded Expert Advisors. The log scale Open, High, Low, and Close prices are buffers:

• No empty values; and

• No repainting.
