Repetitive trading advisor

Dear developer/freelancer

I require a expert adviser for metatrader 4 built with the following features:

• It should issue orders at a interval of time set by the user (me). So it could be every minute (60 seconds), or every 5 minutes (300 seconds) or every hour(3600 seconds), and so on, the time between trades should be a variable set by the me when I'm opening the adviser. This is the most important part of it, instead of having a set of indicators triggering the trade it would be only time that will trigger it. one user defined field here: time to order

• it will also include a pip count to decide whether it is a sell or a buy order. So for very time period it will count the difference between the starting position and the actual price, if the price is lower it will issue a sell order if the price is higher it will issue a buy order. So i guess the simplest way would be to calculate the price difference between t0 and t1 and compare it to 0, if greater than 0 the order will be a buy, if less than 0 the order will be a sell. To write out any errors made by the BID/ASK differences the EA should use the mean price between the two when comparing. 

• every order issued will have a stop loss,a take profit and a quantity input which should also be set by the user. 3 user defined fields here: stop loss, take profit, quantity

• a on/off feature that will allow me to run other trades and not be influenced by this EA

• a liquidity stop, it should not trade more than a percent or a sum of the total available liquidity. one user defined field here: limit amount

•  a profitability test, at a different interval of time than the one for ordering it will check every opened position and if any position shows a profit greater or equal to a set value it should close the trade. so another 2 user defined fields here: one for when to check (user defined field: time to check) and another for which trade to close (user defined field: earning)
