Trade Zone EA - Top coder needed

The Trade Zones are areas defined by a Trade Zone Limit on one side, and no limit on the other side. This means that all trades above/below the Trade Zone Limits are valid, no matter how far the price goes beyond yesterday’s highest high/lowest low.

Trade Zone Limits (TZL) are defined as a % of the difference between yesterday’s highest high and lowest low in the EA input. Let’s say that TZL is = 10% and the difference between yesterday´s highest high and lowest low is 1000 points. Then each of the two Trade Zone Limit lines are placed 100 points (10% of 1000) away from yesterday´s highest high and lowest low towards each other. Use server time to determine day beginning/end.

Entry Lines

The EA uses the ATR value to define the Entry Lines for which a trade is triggered when price opens above it and crosses it from above (sell trade) or price opens below it and crosses it from below (buy trade). 

The ATR value from last candle-close determines the new Entry Lines, so the Entry Lines (potentially) change location frequently. The Entry Lines are placed the number of points derived from the ATR indicator respectively below the current highest high of the day and above the current lowest low of the day – However, the Entry Lines need to be “attached” to a candle-open, so it needs to find the candle-open of the day where the distance from highest high/lowest low to candle-open comes closest to the ATR value at last candle-close, and never less than the ATR value. It is okay to enter a trade if the Entry Line is not in the Sell/Buy Trade Zones as long as the highest high/lowest low is.  

Trade management

Given the nature of the trade management for this EA, it is necessary to create a log file that captures trade history for each currency pair and total account- and currency pair profit/loss. The EA will read from this file in order to determine next lot size.   

The file should be automatically created by the EA and the file should be manually editable. If log file does not already exist when EA wants to read from it, then the EA should create the file and all trades on all pairs will start by the initial lot size listed in EA input. 

Account- and currency pair profit/loss is calculated from the time the log file is created. So if for example the log file is manually deleted, the EA will generate a new log file and profits will be reset to 0 for both the account and each currency pair.
