Heiken Ashi candle sticks trading robot/EA for meta trader 5

I want a trading robot that will be based on Heiken Ashi Candle sticks. I want a situation where once I put the robot on the chart and the heiken ashi turns red the EA will open a sell trade (note: only one trade should be open at a time). When the heiken ashi turns green, I want the EA to automatically close that trade and open a buy trade (note: only one trade should be open at a time). The EA should allow me to put in a series of lot sizes I want the robot to use in opening trades when a particular number of pips is achieved. For example, I put a series of lot sizes (0.01, 0.02, 0.03, 0.06, 0.10), when the heiken ashi turns green and the EA opens a buy trade, the first lot size it will use will be the first in the series, in this case 0.01. Then if the heiken ashi turns red, a sell trade will open like I have explained already. I will put in the number of pips I want to achieve (for example 20 pips) before the EA moves to the next lot size in the series (Please put in a feature where I can see the trades in pips not points). So the robot will keep buying and selling according to the colour of the heiken ashi with the first lot size in the series till the total number of pips is achieved (for example 20 pips). Then the next trade the robot must open will be with lot size 0.02 which is the next in the series of lot sizes, and it continues like that till all the lot sizes in the series have been used and the 20 pips for each has been achieved, then the robot must stop all operations. The option of trailing stops should be added (There should be an off or on button). The default pair should be XAU/USD but it should work on currencies and indices as well. The default timeframe should be 5 minutes but it should work on other timeframes as well. The EA must have a spread filter.

1. Please read the parameters carefully before selecting/bidding for the job.

2. The EA must be able to have 30 lot sizes in the series that it will be picking from.

3. I want the source code when you are done and an NDA agreement.

4. I will require complete assistance for setup and running of the bot.
