Close@Profit is an EA that close orders after defined profit or loss. You can define if to close only trades on current symbol or to close all orders on all symbols, to close only opened trades or also delete pending orders.
The EA looks for trend using three MAs (period 200, 50, 25 or other) and opens orders using the Parabolic SAR indicator. There is martingale in an Expert Advisor, the lot is calculated in percents from a deposit depending on Stop Loss.
This is an EA trading strategy that tries to recover the lost trade. This tactic helps in just the right direction once and the profit takers will be able to stop the previous loss. The game is restarted. It works based on the trend and automatically closes if the trend reverses.
Trailing stop allows you to automatically protect the profits with your positions. It adjusts itself according to the current market rate and the amount of pips you give it to trail behind. Trailing stop is a great tool for the conservative and long term traders as it easily creates protective "airbag" for trades. There are two basic ways to set the trailing stop in your MetaTrader 4 platform - use the built-in tool and attach a special EA that will apply a single trailing stop to all orders.
