- 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.

- 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.
- Dynamic Support and Resistance The "Dynamic Support and Resistance" Indicator is a versatile tool that combines support and resistance levels with real-time market dynamics.

- Multi SellLimitOrders & Multi SellStopOrders Multi Selllimit and Sellstop orders are script files that enable traders to place multiple orders with ease. These orders allow traders to enter the market at a specific price level, or at a specified number of pips away from the current market price, with stop-loss and take-profit levels. By default, the pips value is set to 400, which means the trade will be placed 400 pips away from the current market price for a 5-digit broker. Moreover, the multi Selllimit and Sellstop orders offer traders the flexibility to customize their trading strategies. Traders can set the stop-loss level to zero if they do not use stop-loss, and can choose between a target price or a pip-based entry.
