Martingale / Grid Expert Advisor Forex

Forex Expert Advisor I am looking for a grid trading system that only has one trade open at a time. Below are my thoughts: 1) Let’s say that the market starts at 1.3500, for illustration purposes. (This number will be set, the first time, when the EA is turned on) 2) A grid would be created that is X (we will use 15 for illustration purposes) pips above and below the start level both at one unit (specific value to be set by the user). 3) If the price reaches 1.3515 EA will buy one unit 4) If the price reaches 1.3485 EA will sell one unit 5) If the price reaches 1.3530 EA will sell instruction 3) then immediately buy 3 units 6) If the price reaches 1.3470 EA will sell instruction 4) then immediately sell 3 units 7) If the price reaches 1.3545 EA will sell instruction 5) then immediately buy 7 units 8) If the price reaches 1.3455 EA will sell instruction 6) then immediately sell 7 units 9) If the price reaches 1.3560 EA will sell instruction 7) then immediately buy 15 units 10) If the price reaches 1.3440 EA will sell instruction 8) then immediately sell 15 units 11) If the price reaches 1.3575 EA will sell instruction 9) then immediately buy 31 units 12) If the price reaches 1.3425 EA will sell instruction 10) then immediately sell 31 units 13) If the price reaches 1.3590 EA will sell instruction 11) then immediately buy 63 units 14) If the price reaches 1.3410 EA will sell instruction 12) then immediately sell 63 units 15) Continue the same progression for a total of 100 steps in both the buy and sell directions. 16) If at any time he overall progression shows an overall profit of X pips (15 for illustration purposes, specific unit number doesn’t matter for this calculation only the number of pips) close out all trades and restart the entire sequence from the beginning based on the current value of the currency. (This calculation will not include commissions or the spread values). 17) Only one trade is allowed to be open at a time. The existing trade must be closed out before the next trade is entered. If you have questions please ask. This EA should be easy to program with a few loop functions.
