I want to program an expert advisor to help me with trading

I would like to program an expert advisor to help me trade, as follows:

First: Pending orders are used that are triggered when the candlestick touches the pending order line, ignoring the spread. Therefore, the operating model is as follows:

The blue order execution line is moved on the screen and fixed at the desired location. After locking it in using a button to the right of the line, a red stop-loss line automatically appears. This line can also be moved on the screen and fixed at the desired location. If it is locked above the order execution line, the trade type is a sell. If it is locked below the order execution line, the trade type is a buy. After locking, regardless of the trade type, the order execution line is ready for execution. A third line appears on the screen, which is, of course, the take-profit line. Locking it in place makes the line ready to execute the take-profit order.

Second: A window is created to control some settings, such as the risk amount for each trade, closing all open trades, closing all pending orders, and a button to add an order execution line.

Notes:

1/ If a stop-loss line is set and the trade is ready to be executed, a new line can be added to execute the order via the control window. Note that more than one order can be set at the same time without specifying a specific number.

2/ As explained above, if the order execution line is set, a stop-loss line will appear. Its function before setting is to automatically determine the contract size based on the distance between it and the execution line (the number of points) and the risk amount previously specified in the control window (taking into account if the trading security is not based on points but rather on price alone, such as stocks or indices).

3/ The hold buttons for any line are on the right.

4/ The hold button for the execution line is converted to a close-trade button after the trade is activated. As for the remaining lines, the hold buttons remain so that I can move them even after the trade is activated.

5/ Place the contract size in the center of the stop-loss line so that the contract size changes with the change in the stop-loss line's location before the trade is activated. After activation, the volume remains in the center of the line even if the location is changed.

6/ Split trades and execute multiple trades if the lot size exceeds the maximum lot size provided by the broker.

7/ The control window and pending orders are separate for each screen.

8/ Place the profit amount and profit-to-loss ratio in the center of the execution line so that they are The numbers change with price changes until the trade is closed. They are placed in the middle of the take-profit line based on the line's placement, and thus remain fixed and unchanged with price movement.

9/ The expert advisor must work on all securities, such as forex, metals, indices, and stocks.
