ACI Bollinger Bands


Tired of picking up the indicator settings, wasting precious time? Tired of the uncertainty in their optimality? Are you afraid of the unknown in their profitability? Then the ACI indicator (automatically calibrated indicator) is designed just for you. By running it, you can easily fix these three problems with one simple actionby clicking on a single “Calibrate” button. And in order to achieve the highest efficiency, it is enough to perform only one more action to move the power slider to the maximum.

ACI will save you a lot of time, which can be spent on more useful activities, for example, on vacation, but at the same time the efficiency will increase many times. In addition, thanks to a separate graphical interface, you can not only observe, but also easily change the indicator settings on the fly, while being able to visually select the area for their calibration on the chart.

  • closing price, 
  • opening price,  
  • maximum price for the period,
  • minimum price for the period, 
  • median price, 
  • typical price,
  • weighted average price.

To calculate the quality (profit), traditional input and output signals are used:
If the price crosses the lower level of the indicator, then we have a buy signal. If the price crosses the upper level of the indicator, it is perceived as a sell signal.


The automatic calibrator and the calibrated indicator itself can be controlled thanks to the ACI graphical interface, which reduces the number of actions on your part to a minimum. To start the calibration process, click on the appropriate “Calibrate” button. When the calibration power reaches the specified level, the calibration will stop, or you can stop it by clicking again.

In addition to calibration, ACI also calculates and shows the quality (profit) of the selected parameters of the calibrated indicator on the specified time section of the chart on the fly. The calculation is performed using the specified method in the settings (the “Criterion for calibration” parameter). You can change the temporary area on the chart using levels. To do this, move the cursor to the top or bottom of the level, click to select it and start moving.

If necessary, you can increase or decrease the power (“Power”) of the calibrator by moving the slider clockwise or counterclockwise, respectively, where the dial transparent area allows you to adjust from 0% to 20% of full power, green 20% to 50%, and red from 50% to 100%.

If necessary, you can simultaneously work with several copies of this indicator on the same chart.

The indicator has many settings, ranging from the settings of the calibrated indicator to the settings of the ACI graphical interface.

Calibration criteria. The method of calculating the quality (profit). 
If you select “Total_Net_Profit”, then the quality =
total net profit (in pips) – total net loss (in pips).
If you select “Total_Net_Profit_Total_Drawdown”, then profit =
total net profit (in pips) – total net loss (in pips) –
the total maximum drawdown for all signals (in pips).
Only the closing prices of the bars are used as prices.
