- KA-Gold Bot KA-Gold Bot is an advanced trading advisor specifically designed for gold, utilizing the powerful combination of the Keltner channel strategy and two exponential moving averages (EMAs) - the 10-period EMA and the 200-period EMA. Principle of Operation: The 10-period EMA represents the average price cutting above/below the Keltner band, confirming an uptrend/downtrend. The price being above the 200-period EMA supports the uptrend/downtrend. This indicates that the uptrend/downtrend has been stronger than the previous 10 periods, considering the volatility over the last 50 periods.

- Moving Average with alerts on price crossovers I wanted to build a moving average which would create an alert when the price moves over the line by a user defined amount of points. It creates both bullish and bearish signals depending on the direction of market price moving through the MA. It is designed for slow length moving averages (default is 200-day MA). EDIT: I now added a second version of the indicator which uses Arrow buffers instead of ObjectCreate.
- RectangleTest The EA trades using the Rectangle, EMA and SMA indicators.
