Manual trading system:

Trend Determination: The Course Crystal indicator analyzes current and past price data to determine the overall direction of the trend. If the majority of data points to higher prices, the indicator turns blue. If the data indicates falling prices, the indicator turns red.

Signals to enter a trade: When the indicator changes color from red to blue, this can be a signal to buy. When the indicator changes color from blue to red, it can be a signal to sell.

Risk Management: It is important to always set a stop loss and take profit for each trade to manage your risks. It is recommended to set a stop loss at a level that is above (for buying) or below (for selling) the last high or low.

Exit trade: The trade is closed when the take profit or stop loss level is reached, or when the indicator changes color in the opposite direction.
