MT4 Forex Expert Request

Hello everyone 

I want to configure an expert advisor that works in a certain way at certain times, to be determined by the day and the hour
Or that the trade is activated instantly with a click
I also want this EA to be able to open with only a buy trade, or a sell trade only, or a buy and sell trade at the same time (Hedge)
Maybe use it during the news
The most important thing in making the expert advisor is the sequence in implementing the required steps accurately and immediately
This expert advisor depends some of the work on the trailing stop process, but in a special way

Example of a buy trade

When the price moves from point A (entry price) to point B (current price), point C (initial stop loss) is moved to point D (new stop loss).

The first distance is the distance between point A (the entry price) and point B (the current price).

The second distance is the distance between point C (the initial stop loss) and point D (the new stop loss).

The third distance is the distance between point B (current price) and point D (the new stop loss)

, which makes point D (the new stop loss) change up as point B (current price) changes up, but remains constant when the current price moves down to maintain the profit earned in the case of a buy trade .

# In the case of a sell trade, point D (the new stop loss) changes downward as point B (current price) changes, but remains constant when the current price moves up to maintain the profit earned
