Update an ea - order open condition and add trailing the profit using profit money

dear programmer i am having an expert advisor and need to change the order open condition and change the trailing profit for profit money based not price place value based. change the stoploss values to trail the profit for all the buy orders open using the magic number. it means it should set the stop loss value at the single point for each and every buy order or sell order. not separate for each and every buy or sell orders. this ea has take profit after reach the particular profit. but i want to trail the profit and this ea should close the orders at the maximum profit amount.
