EA that places multiple Pending Orders(Buy & Sell) based on SMA crosses

Dear All

I would like some help in coding an EA. I'm not good at it all.

My query, is it possible to make the EA Open hedge pending orders?

I only trade in Gold with the following 2 strategies:

1. if 12 SMA crosses above 20 SMA, then I want to open a set of buy stop & sell limit orders as below;

For e.g. the current price when SMA crosses is $1300.00 then;

1st buy stop @ 1302.00 & sell limit @ 1302.50

2nd buy stop @ 1303.00 & sell limit @ 1303.50

3rd buy stop @ 1304.00 & sell limit @ 1304.50

4th buy stop @ 1305.00 & sell limit @ 1305.50

2. if 12 SMA crosses below 20 SMA, then I want to open a sell stop & buy limit orders as below;

For e.g. the current price when SMA crosses is $1300.00 then;

1st sell stop @ 1298.00 & buy limit @ 1297.50

2nd sell stop @ 1297.00 & buy limit @ 1296.50

3rd sell stop @ 1296.00 & buy limit @ 1295.50

4th sell stop @ 1295.00 & buy limit @ 1294.50

I need the EA to check on regular intervals if there are any old orders present. EA shold accept the order size manually and then place the pending orders based on the above SMA crosses. I'm currently trading on the MT4 platform with a virtual server and have searched everywhere for an EA to do this. Only closest I have found is your EA for MT5 platform (https://www.mql5.com/en/articles/723) but I would rather stay on MT4.

Please I hope someone can assist me.

thanks
