StockCharts vs TradingView for custom indicators

Compare the output you need

A StockCharts scan expression selects securities. A Pine indicator calculates series and draws them on a chart. These tasks overlap when a rule uses standard indicators, but they are not interchangeable development environments. The official feature, scanning and Pine references below describe the supported workflows.

Task 1: find stocks above two moving averages

Define the same test before comparing platforms: a saved list of US stocks, daily bars, and a completed session. A symbol passes when its close is above its 20-day simple moving average and that average is above its 50-day simple moving average. This is a comparison procedure, not a measured result.

• A saved scan count is not the number of stocks scanned or the number of live alerts.
• Pine Screener currently permits one indicator per screen, calculates the latest 500 bars and restricts supported timeframes and request calls. A script working on a chart can still fail its screener requirements.
• Historical scan dates help investigate earlier matches. Return calculations additionally require explicit entries, exits, sizing and transaction assumptions.

Task 2: draw your own band and mark confirmed crossings

Suppose the required line is the 20-bar SMA minus 2.5 times the 14-bar ATR. You also want a marker when the bar closes crossing below that line. In StockCharts, check the available overlays and add-ons against that exact formula; a similarly named stop can use different math. TradingView lets you express the formula directly in a Pine indicator. This example uses the chart timeframe and is a moving band, not a ratcheting trailing stop.

• Use a standard daily candlestick chart for the same-task comparison. Wait for enough bars to initialize both calculations.
• The band can move up or down. The crossing compares each bar with its own band value; it is not an order to exit a position.
• The marker requires a confirmed chart bar. To receive notifications, add the indicator and create an alert using Confirmed band breach with Once Per Bar Close.
• Changing the indicator inputs on the chart does not update an existing server alert. Recreate the alert with the intended settings.

//@version=6
indicator("Custom SMA and ATR band", overlay = true)

int maLength = input.int(20, "SMA length", minval = 1)
int atrLength = input.int(14, "ATR length", minval = 1)
float multiplier = input.float(2.5, "ATR multiplier", minval = 0.1)

float average = ta.sma(close, maLength)
float lowerBand = average - multiplier * ta.atr(atrLength)
bool crossedBelow = ta.crossunder(close, lowerBand)
bool confirmedBreach = barstate.isconfirmed and crossedBelow

plot(average, "SMA", color = color.blue)
plot(lowerBand, "Lower ATR band", color = color.teal)
plotshape(confirmedBreach, title = "Confirmed breach", style = shape.triangledown, location = location.abovebar, color = color.red, size = size.small)
alertcondition(confirmedBreach, "Confirmed band breach", "The bar closed crossing below the SMA minus ATR band.")

Alert timing is part of the rule

StockCharts Technical Alerts documentation describes daily-data conditions checked during market hours, with alert-engine data refreshed every 3 to 5 minutes and notification at most once per day for a given alert. That differs from a promise of tick-by-tick monitoring. TradingView alert behavior depends on the condition, frequency and script execution settings.

• StockCharts lists email, text and web notifications. Confirm delivery options and account limits before relying on a particular channel.
• Pine alert code exposes conditions; it does not create a running alert by itself. TradingView stores a snapshot of the script and settings when the alert is created.
• A TradingView webhook sends an HTTP POST to an external URL and requires two-factor authentication. Receiving that request, validating it and placing an order are separate integration steps.
• Check alerts with a notification-only workflow before connecting any external execution service.

Compare total cost, including the feed

The prices below were checked on October 16, 2026. StockCharts publishes USD monthly rates. TradingView localizes currency and billing offers, so use its current checkout for an equivalent quote. Compare the same billing period, tax treatment, required features and data entitlements.

• Buying a higher software tier does not automatically purchase every exchange feed.
• A live price from one venue is not proof of identical prices or volume across platforms. Check the symbol source and session.
• Pineify helps author Pine Script. It does not replace either charting subscription, exchange data entitlement or broker account.

Choose with one saved workflow

Start with StockCharts if ChartLists, RRG and scan clauses already express your research process. Start with TradingView if editing the indicator source or modeling strategy orders is the requirement. This recommendation follows the documented capabilities; it is not a claim that either platform produces better trades.

• Keep your original symbol list and written rules. Translate symbol formats and formulas separately; do not assume a ChartList export is a ready-to-import TradingView watchlist.
• Record the chosen feed, timeframe, session, indicator settings and notification frequency before comparing results.
• For a custom Pine implementation, review the generated source, request syntax checking and inspect chart signals before expanding the rule.
