I want an mt4 indicator converted into a expert advisor

I have a non repainting mt4 indicator I want converted into a expert advisor. The indicator generates signals by painting a white arrow for buy and a red arrow for sell. Below is how I want the Expert advisor to work.                                                Once the indicator paints a white arrow from below the E.A should buy immediately and if the indicator paints a red arrow from above the E.A should sell immediately.                                                              EXITING OF ORDERS.                                                         If the indicator had generated a buy white arrow and had a buy order then after some time it generates a red arrow for sell the E.A should close the buy order regardless of whether in profit or loss and place a sell order because of the new red arrow painted meaning selling.                                                            RISK MANAGEMENT                                                       The programmers should insert a parameter where I will put my maximum number of pips I can allow an order to go against me.                                                   I.e  if my maximum drawdown is 50 pips and I had a buy order but the market moved against me by 70 pips then the E.A should close my loss at 50 pips and wait for the next signal.                                               TAKE PROFITS.                                                                   The programmer should put me a parameter where I will place the number of pips I want to take as profit when orders move on my favour.                                    I.e  if I had my take profit at 10 pips and I got a buy order and the market continued to buy for 50 pips then the E.A should take profit immediately the market moves 10 pips away from entry price to my favour.                                                                                   ADDITIONAL COMMANDS.                                                I want the E.A to also take care of its losses                EXAMPLE.                                                                            I have set my take profit at 10 pips                                my maximum drawdown at 50 pips                                 fixed lot size at 0.02                                                            Then the E.A generates a buy order at 0.02 but unluckily the E.A gets a sell order and its exits the buy order with a loss of - 4 usd so what the E.A should do in the next sell order is make sure that it uses a lot size big enough to generate 6 usd with the set take profit for our case take profit is set at 10 pips... so the bot should do a quick math and find a suitable lot size that will be enough at 10 pips to make back the previous loss and a small profit on top.
