How to write a simple expert advisor

[Trader1529]

Good morning everyone, 

I want to write a simple expert advisor, but I don't know how to do it. Can someone help me?

I want that my EA do this:

  - At "Time T" it opens "Buy" or "Sell" position with "Amount z"

  - It close the position when TakeProfit is "x percentage" of "amount z"  or StopLoss is "y percentage" of "amount z"

  

 For example:

 I have 100$ on my account

 I set:

  - Time T = 14:00:00

  - Position = BUY

  - Amount z = 50$

  - TakeProfit = 10%

  - StopLoss = 15%

  

the expert advisor at time 14:00:00 it open a buy position of 50$ [Lots= ("Amount z" * "Leverage"), if the leverage of my account is 100, the lots to open are 5000].

When the profit is of 5$ or when the loss is 7.5$ the position will close.
