Pinescript to MQL5 EA conversion

Hi Guys, 

I have a pinescript strategy that i want to convert to MQL5 to use as an EA in metatrader5 . The script is based on a daychart bar candles and opens at the open of each bar and closes on either  a Stop loss or take profit if neither the stoploss or take profit is executed then the strategy closes the trade a few seconds before close. If the previous trade was a losing trade then it adds one to the lot size for the next trade .

There is one difference in the strategy i have attached and the strategy i want in MQL5 and that is that i want the strategy to close all trades before the close , whereas the existing strategy holds the trade open to the next days open.
