EA based on macd

I’m looking for someone who can built the following EA!

EA wich opens trades based on regular MACD: 12,26,9

With a input of the lotsize

with a stop loss: 50 pips

With a take profit from 150 pips

with a trailing stoploss from 40 pips but but it should only trail the stoploss every 50 pips!

Example: if the trade hits the first 50 pips in possitive direction the trailing stop should move the Stoploss toward the level where the trade still would be 10 pips in profit. When the trade hits the 2nd time 50 pips (the trade is now 100 pips in possitive direction) the trailing stop should move the stoploss toward the level where the trade still would be 60 pips in profit. And then when the trade hits another 50 pips the trade would bes hut down by the Take profit.

Not possible to open more then 2 trades at once
