MT4 scripts required to read from csv , I have the mt5 ones

Hello friends;

I have   an independent script for Delete all pending orders and one single  MT5 scripts doing the following :

1- read from csv  to BuyStop limit

2-  read from csv to sell stop limit

3-  read from csv to sell limit

4-  read from csv to buy limit

5-  read from csv to sell stop

6-  read from csv to buy stop

it allows me to place the order , comment, time and contract size by just dropping on any chart , not the current pair chart

the above are all in one script , where in the csv i write the pair type and the script understand which type of trade and all other information  (will provide you with my existing CSV file for reading the same structure/sequence)

I need the for mt4 the same :

1- Delete all pending orders

2- read from csv  to BuyStop

3- read from csv to sell stop

4- read from csv to sell limit

5- read from csv to buy limit

you kindly to provide the source code and explanation
