MQL5: Drawing lines and placing order based on manually drawn Fibonacci-Object

1. The program shall draw lines visually on the chart based on Fibonacci-Objects drawn manually by the user:

• The manually drawn fibonacci-object will have 4 levels: 0%, 100% and Fib-Level 1 and 2 (of which the %-level may vary) and will be placed by the user manually in the chart as a starting point.
• Upon clicking on a button or pressing a key, the program shall draw the following on the chart:
• 4 lines which are equal to the levels of the manually placed fibonacci-object and each of those fib-levels shall have in addition lines that are offset from the fib-level by +/- x pips (x shall be a changeable input, and different inputs shall apply in case the fibonacci-object is facing up- or downwards).The 100%-fib-level shall have 3 offset lines, the other fib-levels only 1. 
• All those levels placed on the chart shall have the same color and the same width as the manually drawn fibonacci-object.
• Furthermore, the following shall be displayed next to the drawn lines on the chart: a) the pip distance between the drawn 0%- and 100%-fib-level, and b) the ratio between i) the distance between the offset-level of the 0%- and offset-level 2 of the 100%-fib-level, and ii) the distance between the offset-level of the 100%-fib-level and offset-level of the fib-level 2.
• The user shall be able to draw anytime new lines based on a newly placed fibonacci-objects (whereas the previous lines have to remain on the chart).

2. Once those levels are drawn on the chart by the program, two further functionalities shall be available to the user:

• Deleting a specific set of levels (a "set of levels" means the levels based on one fibonacci-object).
• Placing an order based on a set of levels that are already drawn on the chart: 
• Order prices: Stop-loss = offset level of 0%-fib-level, limit price = offset level 2 of 100%-fib-level, stop price = offset level 3 of 100%-fib-level. 
• The user shall be able to choose to place either a stop-limit order, a limit-order, or a stop order.
• The position size of the order shall be calculated automatically based on an input amount in any main currency.
• Once an order is placed (filled or unfilled), it shall be possible to change the target and/or stop-loss price manually.

This shall be the first version. If it works well, I am considering developing this program further step-by-step with the programmer.
