History compression is a process of “archiving” the history of trading operations (buy/sell orders) on live accounts in MT4. As a result of the compression, a number of closed trading positions are converted into a single balance operation (Balance type in MT4 Account History) with the “History compression” comment, which displays the total financial result (profit/loss + commissions + swaps) for the “compressed” orders at the time of archiving.
Compression of trading operations will not affect any open positions. Only closed positions can be archived. The Company may compress the history of all trading transactions older than 3 months.
Trading accounts history compression can only take place on a weekend (Saturday) at the time of a scheduled trading servers’ optimization. Kindly note that at the time of optimization, trading in cryptocurrencies will not be available.
Trading history compression is a standard part of trading servers’ optimization, which is regularly carried out by all brokers. Its main goal is to further optimize our trading servers in order to ensure the maximum stability and efficiency for our clients since optimization has a direct impact on the order execution speed.
