Using Bid and Ask Lines to Read Execution Prices

Summary

This indicator description focuses on displaying clearly labeled bid and ask price lines on a trading chart. The visual aid is intended to reduce confusion between the two quotes when considering order placement. It explains that a buy order reaching the current ask and a sell order reaching the current bid are treated as immediate executions in the described context.

The author suggests watching the ask when planning a buy and the bid when planning a sale, with the aim of judging where an order would execute relative to the candle’s range. This can help distinguish the executable quote from the chart’s broader price display. The document offers no data, testing, or decision rules showing that the lines improve entry quality or profitability. Actual fills can depend on order type, liquidity, and market conditions, so the indicator is best understood as a quote-visualization aid rather than a standalone trading method.

Key ideas

  • The indicator labels bid and ask prices to make them easier to distinguish on a chart.
  • The description associates immediate buys with the ask and immediate sells with the bid.
  • Visible quote lines may help traders assess execution prices alongside candle ranges.
  • The document provides no evidence that this display improves trade outcomes.
