This EA works like this: In backtest, it reads history file with external kernel32. dll and knows the CLOSE PRICE of 8 hours in advance. Then, it draws a so-called pivot line to trade around with using reversal strategy. If the current one 1 minute, 5 minute (if you attach to it) price is above the line, it trades sell (because finally the price will be closed at the line), and if the price is below the line, it trades buy (same as sell logics). This is a backtest trick to produce amazing result. If you don't set SL, TP, the profit is even much better in backtest.
However, when the history file ends, it will take a random price nearest to the close price of the current 4 hour chart as the pivot to trade. This is random, and depends on luck or bad luck like gambling.
In a nutshell, it used a trick to produce amazing backtest, but in real trading it is just gambling. If you are lucky, you may win. If you are not, your account will be blown.
Never use this EA if you want to protect your capital. It must be a scammer originally.
