Simple EA on MT4

Dear programmers

I need to code simple EA which will trade mostly on EUR/USD and other major pairs under these market conditions 

Mode 1 will be: 

• When spread is less than 1 ( I want that to be adjustable from 0 to 0.1 , 0.3 , 0.6 up to 1 or current spread ) 
• The EA will put random  Buy/Sell orders - only if spread condition meets criteria 
• I want the SL/TP manually set
• Maximum opened position in the same time will be 5,4,3,2,1 manually set
• I want trailing stop manually set
• I want trailing step manually set
• Lot size with microlots

 Mode 2 will be:

• opens buy as a first trade if that hits the profit opens another buy and carries on until buy orders are succesful or if first buy hits SL opens sell if that hits SL opens buy and on and on trying to follow the trend ( entry the market immediately )
• Opens only buy positions ( entry the market immediately )
• opens only sell positions ( entry the market immediately )
• I want the SL/TP manually set
• I want trailing stop manually set
• I want trailing step manually set
• Lot size with microlots

Thank you
