An example will be printed in the Experts tab when you unload the EA from the chart). The EA checks the position of the price and the iAMA (Adaptive Moving Average, AMA) indicator to place an initial pending order.

• If the Close price of bar #0 is above the indicator, a pending Buy Stop order will be placed at the upper round price.
• If the Close price of bar #0 is below the indicator, a pending Sell Stop order will be placed at the lower round price.

Lifetime is set for each pending order: Life time of the pending order (in hours) is added to the last known server time.

Separate trailing methods are applied for BUY and SELL positions. They are configured in Trailing Stop BUY and Trailing Stop SELL.
