Modify my Source MQL4

I have my EA source code that I need to modify.

things to modify are:

************************************************** ** ** ** ** ** **************

all the following modifications are optional to the original that this EA already has, that is, they will work in parallel with the original

the following features are optional to the default ones

Distribute the default value as it is now or modify it as follows

1-Add control option enable/disable propagation control

If this option is activated, take positions with the margin set below

maximum spread allowed example 0.20 (configurable)

make hidden profits

2-Take the default perk as it is now or modify it as follows

customize take profit yes/no

take profit in pip: example 100.0

Forex Take Profit: Example 1.0

3-enable/disable hidden SL

customizable in pip and currency

4-add yes or no option of a chart (so you don't have to put the ea on each different chart)

-delete where it says symbol information and place it like this

Symbols if they are custom place them too: AUDCAD, EURCAD, EURGBP, EURAUD, EURUSD, GBPUSD, USDCHF, AUDCHF, AUDUSD, CADCHF, EURCHF, GBPAUD, GBPCAD, USDCAD

6 maximum symbols at the same time (ie maximum positions of different currencies), for example

allowed 3

eurusd, gbpusd, nzdusd then it won't take any more until they finish

-where it says preset type modify it with "Auto Configuration"

7-add special hidden tracking i.e if position started at -0.20 and changed to 0.50 start tracking i.e if it drops below 0.15 close position make it configurable

configurable in pip and currency

8--news protection on/off

low impact (on/off)

time before (minutes)

time after (minutes)

normal impact (on/off)

time before (minutes)

time after (minutes)

high impact (on/off)

time before (minutes)

time after (minutes)

draws in the window the news of the whole week red the high impact, normal yellow, white low impact, draws the times of each one, that lasts 1 week and then they are erased

if activated, do not take positions only to the currencies that are affected during the set time

9-change the colors of the candlestick chart by which the image "chart1" will be sent

place a background image to be sent "wings"

place an image of the info window "logo"

the news and timelines and candles should look like this image

10-the comments part will be modified so that it is optional to fix that it cannot be changed or to be able to change just write in comments how to do it

11-solve the licensing system working fine

12- the information box that the EA shows will modify some information that it will show but that is at the end when all the above is

a summary of the total earned and the maximum reduction will be added

I need every part of the code with comments every start and end of the function inside the code to understand and know about the modifications.
