Specification

Dear developer, 

I need an EA which would open* an existing excel file (C:/Book1.xlsm) and read the value of cells in Sheet1: 

   - A1 will represent the calculated (desired) amount of opened position in lots,
   - B1 will show the direction (1 means BUY, -1 means SELL). 

EA should open or close position(s) in MT4 every time Cell A1 or B1 changes their value (recalculated by a formula), in order to adjust the amount of open positions in M4 with Excel calculations. So, there can be 3 possible cases:

   - A1 increases its value => open 1 new position.
   - A1 decreases its value => close one or more positions. Occasionally, some positions will have to be closed partially. Closing order: last opened should close first, etc.
   - B1 (& A1) changes value (direction) => close all opened positions and open 1 new position if A1 > 0. If A1 = 0, no positions should be opened. 


If EA will be attached to EURUSD chart, it will control all EURUSD positions on the account, but it should not interfere with other pairs. EA will be attached to at least 8 pairs, so if it is necessary, I can manually change the magic number or a symbol in EA code (as I will manually change cells location (from A1 to A2) when attaching EA to a second chart, etc.).


Maybe you will find this script helpful, allegedly, it can enable MT4 to exchange data with MS Excel:

*if this is possible, it would be ideal that MT4 can read from an already opened Excel file. 

Thank you and kind regards.
