Why these guides

When a trading platform breaks, you need the fix fast, not a forum thread. Each guide lists the exact symptom, the likely cause and a numbered fix that is known to work, covering connection errors, order errors, indicators and Expert Advisors, alerts, data and performance. If you trade on MetaTrader 5, do not miss the WebRequest allowlist fix, which is the most common setup issue for indicators like Market Structure Pro. If you are on a prop-firm platform such as DXtrade, Match-Trader or TradeLocker, check the rule-related pages first: a great many "platform faults" there are actually an account rule being enforced.
