Good Gbbi Strategy

This strategy opens a single position at a specific hour of the day based on the difference between historical open prices.

Logic

  • Works on hourly candles by default.
  • At TradeTime hour the strategy compares the open price from T1 bars ago with the open price from T2 bars ago.
  • If the older open is higher than the recent one by DeltaShort points a short position is opened.
  • If the recent open is higher than the older one by DeltaLong points a long position is opened.
  • Only one trade per day is allowed. Trading is enabled again after the hour is greater than TradeTime.
  • Each position is protected by individual take-profit and stop-loss levels and can be forcibly closed after MaxOpenTime hours.

Parameters

Parameter Description
TakeProfitLong Take profit distance in points for long positions.
StopLossLong Stop loss distance in points for long positions.
TakeProfitShort Take profit distance in points for short positions.
StopLossShort Stop loss distance in points for short positions.
TradeTime Hour of day when the entry conditions are checked.
T1 Number of bars back for the first open price.
T2 Number of bars back for the second open price.
DeltaLong Required difference in points to open a long position.
DeltaShort Required difference in points to open a short position.
MaxOpenTime Maximum position holding time in hours, 0 disables the check.
CandleType Candle type to process.

Notes

The original idea comes from the MetaTrader expert advisor GoodG@bi. This port uses StockSharp high-level API and processes only finished candles. Ensure that the security's PriceStep is configured correctly to interpret point values.
