Combo Right Strategy

Implementation of strategy converted from MQL script combo_right.mq5. The system combines a basic CCI signal with three simple perceptrons working on price differences.

Logic

Basic Signal – Commodity Channel Index (CCI) value. Positive values favour long trades, negative values favour short trades.
Perceptrons – Each perceptron looks at a set of shifted closing prices and applies linear weights. The mode parameter Pass selects which perceptrons are active:
- 1: only basic CCI signal.
- 2: sale perceptron can override CCI and open short positions.
- 3: buy perceptron can override CCI and open long positions.
- 4: general perceptron supervises both buy and sale perceptrons.

If an active perceptron issues a signal, it replaces the basic CCI output. Otherwise the CCI value is used.

Parameters

TakeProfit1, StopLoss1 – profit and loss targets for the basic CCI signal (in ticks).
CciPeriod – lookback period of the CCI indicator.
Weights and periods for each perceptron (x12, x22, …, p4).
Pass – operation mode.
Shift – bar index used for price data (0 current, 1 previous).
Volume – trade volume.
CandleType – candle type for calculations.

Indicators

CCI.
