Trailing Stop Parameters

Long-side, highest-close reference only. The sample is synthetic. No orders, fills, P&L, short positions, or restart after a stop crossing are modeled. ATR warm-up bars have no stop; a nonpositive ATR reference is not an executable sell stop.

What is a Trailing Stop Loss Strategy?

A long-side trailing reference rises as its reference price rises and does not move down. An actual stop order also needs a broker, trigger convention, and execution rules. Its fill can differ from the stop price, particularly across a gap. This page submits no orders and does not model that execution.

This tool uses the highest close since the first uploaded row, including the ATR warm-up interval. Percentage mode multiplies that close by one minus the percentage. ATR mode uses the highest close minus a Wilder ATR multiple, ratcheting upward only. A crossing does not terminate or reset the line. The values are descriptive reference levels, not investment advice or a ranking of profitable parameters.

How to Use This Trailing Stop Visualizer

  1. 1

    Prepare Your Price Data

    Export historical price data from your broker or trading platform. You need date, high, low, and close prices in CSV or JSON format. Download our sample file to see the exact format required.

  2. 2

    Upload Your File

    Choose a CSV or JSON file up to 2 MiB. Use ascending, unique YYYY-MM-DD dates and 2–5,000 valid price rows. Invalid imports leave the existing series unchanged.

  3. 3

    Choose Your Stop Method

    Select percentage distance from the highest close or an ATR multiple subtracted from that same highest close. Both modes show a long-side reference only.

  4. 4

    Adjust Parameters

    Percentage must be above 0 and below 100. ATR period must be an integer from 1–100, with a multiplier above 0 up to 10. Defaults are examples, not recommended settings.

  5. 5

    Analyze the Results

    Compare the close and reference lines. ATR starts only after a full seed window. The chart does not determine which bar would fill a stop or what return would result.

Frequently Asked Questions

What does this trailing stop visualizer calculate?

It plots a long-side reference level from the highest close in your uploaded daily series. Percentage mode uses highest close × (1 − percentage). ATR mode subtracts a Wilder ATR multiple and never lowers an established line. This is a continuous indicator illustration, not a simulation of entries, fills, exits, or profit.

How does percentage mode work?

At a highest close of 100 and a 5% setting, the level is 95. A later highest close of 110 raises it to 104.50. A subsequent lower close leaves it unchanged. High prices within the bar do not raise the reference: this implementation uses closes.

How does ATR mode handle the first bars?

True range uses high minus low and gaps from the prior close; the first row uses high minus low. The first ATR is the mean of the selected number of true ranges. Later values use Wilder smoothing. No ATR stop is plotted before that seed exists. Thereafter the level is the larger of its prior value and highest close minus ATR times the multiplier.

Does crossing the line represent an executed stop?

No. The line continues after a crossing and does not reset or create a trade. Actual broker trigger rules, gaps, slippage, fees, and intrabar price paths are not modeled. A stop price does not guarantee an execution price. This chart cannot establish which parameter is profitable.

What files can I load?

Use a CSV with date, high, low, close headers or a JSON array with those fields. Dates must be unique, ascending YYYY-MM-DD values. Supply 2–5,000 rows, positive finite prices, and a close between low and high. The limit is 2 MiB. The initial 20-row example is synthetic. Parsing and calculations occur in this page; this tool does not send the file to a server or save it across reloads.
