What is Standard deviation channel 4line?
Standard deviation channel 4line is a MetaTrader 4 indicator published on the MQL5 Market by Chao Jian Liu, priced at $30 USD. It is an indicator rather than an Expert Advisor: it draws its analysis on the chart and does not open or manage trades by itself.
Does Standard deviation channel 4line work on MT4 or MT5?
Standard deviation channel 4line runs on MetaTrader 4, not MetaTrader 5. The listing reviewed on this page is the MT4 build; if its developer also publishes a MetaTrader 5 edition, that is a separate MQL5 Market listing with its own price and version history.
How much does Standard deviation channel 4line cost?
Standard deviation channel 4line is a paid product listed at $30 USD on the MQL5 Market, the price recorded when its listing was last checked on 2026-10-06. It is sold and downloaded through the developer's (Chao Jian Liu) page on mql5.com; FxRobotEasy neither sells it nor hosts the file.
Is there a verified track record for Standard deviation channel 4line?
FxRobotEasy has not traded Standard deviation channel 4line on a live account, so no independently verified track record for it is published here. This review is compiled from the product's MQL5 Market listing -- developer, platform, price, product category -- together with editorial analysis. Any back-tested or simulated figures shown alongside it are simulations rather than live trading results, and any performance claim you find for Standard deviation channel 4line elsewhere comes from its developer or from a third party.
