Distinguish the chart price from the closing price
If a gold chart records Bid quotations while the stop-loss of a short position is triggered using Ask quotations, Ask can reach the trigger level even when the Bid chart never touches it. This explains one possible display discrepancy but does not establish that any specific execution was right or wrong. The chart's price basis, applicable trigger quotation and product rules must be checked against execution records.
Bid is the price at which the quoting party is willing to buy, while Ask is the price at which it is willing to sell. In common over-the-counter quoting arrangements, traders sell at Bid and buy at Ask. The difference is the spread. Closing a short position requires buying back, so a short stop-loss is tested against Ask under these rules, while a long stop-loss is tested against Bid.
MetaTrader 5's general trading principles describe these stop conditions, while noting that exchange-traded products may follow their exchange's rules and commonly use Last transaction prices for triggering. OTC rules must not automatically be applied to gold futures, exchange instruments or every other platform.
The chart's price basis also matters. MetaTrader 5's chart settings documentation explains that candles can be formed using Bid or, for certain instruments, Last prices. An Ask line displays the latest Ask. A price labeled current on a chart is therefore not necessarily the trigger price used for every order.
This article assumes an OTC gold mechanism in which the chart is constructed from Bid and short stops are checked against Ask. It does not establish the actual execution rules for any specific Wang Wang Gold account. Those require the relevant product, account and platform documentation.
The chart may miss the stop even when the spread stays constant
Assume an existing gold short has a valid stop-loss at USD 2302 per ounce. The following are two separate hypothetical quotation paths recorded in Beijing time, with all prices in USD per ounce. They are neither current market quotes nor actual trades. Only three quotation points are supplied for each path, without assuming other intervening quotations.
| Path and time (Beijing) | Bid | Ask | Spread | Ask ≥ 2302? |
|---|---|---|---|---|
| A, 10:00:00 | 2300.0 | 2300.4 | 0.4 | No |
| A, 10:00:01 | 2301.0 | 2301.4 | 0.4 | No |
| A, 10:00:02 | 2301.6 | 2302.0 | 0.4 | Yes |
| B, 10:00:00 | 2301.5 | 2301.8 | 0.3 | No |
| B, 10:00:01 | 2301.5 | 2301.9 | 0.4 | No |
| B, 10:00:02 | 2301.5 | 2302.1 | 0.6 | Yes |
In path A, the spread stays at 0.4. Bid peaks at 2301.6, yet Ask reaches 2302.0 and satisfies the assumed stop condition. The existing difference between Bid and Ask is sufficient to create the appearance of a stop being reached without the chart touching it, even though the spread did not widen.
In path B, Bid remains unchanged, while Ask rises as the spread widens from 0.3 to 0.6, eventually satisfying the condition. Widening spreads can therefore matter, but they are not the explanation for every such case. Neither path specifies an actual fill time or price.
The same conclusion cannot simply be applied to a long position. Under the assumed rules, long stops are tested against Bid, so an Ask quotation reaching a level does not mean Bid reached the corresponding long stop. First identify the position direction, the buy or sell action needed to exit, and the applicable trigger conditions.
Displaying the Ask line cannot reconstruct historical triggers
On platforms that support it, showing an Ask horizontal line helps monitor current two-sided quotations. However, the latest Ask line is not a complete historical series of Ask candles. Enabling it after an event does not recover the historical Ask high. If spreads vary, adding today's spread to an earlier Bid high does not reconstruct the earlier Ask high.
A single Bid candlestick records OHLC values on that price basis, not the spread at every quotation time. The Ask high may have occurred at a different moment from the Bid high. Converting one into the other using a fixed offset is justified only when the spread was demonstrably constant, data were complete and both quote streams were synchronized throughout the relevant interval.
A useful review seeks historical Bid and Ask quotations for the same instrument and provider, the effective stop level at the relevant time, order status and actual fills. Server time must be converted to Beijing time using the time-zone relationship applicable then. Quotes from different sources or moments should not be combined as though they belonged to the same observation.
Also check whether the screenshot shows a candle's full high, only its body or close, or an unfinished intrabar image. The absence of a screenshot at a particular moment does not prove that a triggering quote never existed. Bid OHLC data alone are generally insufficient to establish the Ask path, and missing information should remain explicitly unresolved.
A stop trigger and the executed fill price are separate questions
Whether the stop condition was met and at what price the order was filled are different issues. Path A establishes only that Ask reached 2302. It does not guarantee that the short was bought back at exactly 2302. Order execution rules, liquidity and moving prices can change the outcome. See Stop-Loss Triggers and Actual Execution Prices.
Under the assumed quotation-based rule, the condition is assessed when the relevant quote reaches the level, rather than waiting for the candlestick to close. A technical strategy may require closing confirmation, but that does not automatically change the execution logic of an already active stop. Chart-reading rules and order execution rules should be recorded separately.
If the position was closed, verify why it closed. Manual exits, stop-losses, take-profits and margin-related forced liquidations do not necessarily follow the same triggers. See Insufficient Margin and Forced Liquidation. One chart line cannot establish which event occurred.
Do not remove risk controls to solve a chart discrepancy
If order records and a chart appear inconsistent, investigate the quotation basis and evidence first. Removing the stop or simply moving it farther away to avoid unseen triggers is not a substitute for understanding execution. Spread, volatility, stop distance and position size should be evaluated together; see Stop-Loss Distance and Position Risk.
Risk warning: This article provides education about quotations and charts, not personalised investment advice. The hypothetical paths do not represent actual platform spreads or guaranteed fills. Stops do not guarantee an exact execution price or eliminate slippage, liquidity and margin risk. Without complete quote and order evidence, a screenshot alone should not be used to declare an execution abnormal. Margin trading can result in loss of principal.
