Best Forex Indicator for TradingView: Choose by Task

Choose the quote source before comparing indicators

EUR/USD is not a complete dataset identifier. TradingView explains that ICE forex symbols combine contributions from multiple sources, while other feeds represent individual brokers. Provider trading hours and volume coverage can differ. Record the symbol prefix, interval, timezone, session and test dates; a feed change is a new experiment.

• Use the same source for every candidate. Do not compare one indicator on OANDA:EURUSD with another on FX_IDC:EURUSD and attribute the difference only to the formula.
• Separate chart price from execution price. TradingView documents that FOREX.com charts use mid prices while orders execute at bid or ask. A line touched on that chart is not proof of an executable fill.
• Write session filters with an explicit timezone and daylight-saving policy. A London-session rule must not silently shift when clocks change.

When tick volume is usable, and when to leave it out

Tick volume can describe activity in the selected feed. It cannot establish the cash value traded across the forex market. A volume-weighted indicator inherits that input limitation, so label what it measures before using it to confirm a price signal.

• TradingView states that FOREX.COM forex symbols lack volume data and ICE volume is available intraday but not on daily-based timeframes. Verify the exact symbol before choosing a volume-dependent tool.
• For an optional relative-volume test, compare a completed bar with prior comparable session bars on that feed. A session opening should not be treated as exceptional merely because the preceding session was quieter.

Compare candidates on the same sample

The following hypothetical EUR/USD one-hour experiment is a specification, not an executed backtest. Choose one feed and a continuous date range before looking at results. Reserve the final third chronologically for evaluation, and keep it untouched while selecting settings on the earlier period.

• Keep execution identical: one long position at a time, next-bar market entry, and fixed units chosen before the test. Freeze 14-bar ATR at the signal close; place a stop two ATR below the entry fill and a target four ATR above it. Also exit after a close below the EMA, at the next available market fill.
• Keep exits, position size, session rules and costs unchanged across versions. Use standard candles. Record ambiguous bars where both stop and target are touched and review the emulator assumptions.
• Record trade count, average net trade, maximum drawdown and net result after costs for both periods. A version that rejects many signals may leave too little evidence to assess.
• After choosing rules, evaluate them on a later untouched period or another preselected pair. Repeatedly changing settings after seeing that evaluation makes it part of development.

Costs and signal timing can outweigh the indicator choice

Use broker-specific spread, commission and financing assumptions, then repeat the test with less favorable costs. Slippage is uncertain, especially around economic releases. A backtest on chart OHLC does not recreate historical bid/ask execution or guarantee that a stop limits the realized loss.

• Illustrative cost check: if a complete trade moves 8 pips in your favor before costs and the assumed round-trip drag is 2 pips, the remaining move is 6 pips before other charges. This arithmetic is not a measured strategy result.
• Compare confirmed signals. EMA, RSI and other price-derived readings move on an open candle; waiting for close changes the timing of the rule.
• Audit higher-timeframe inputs separately. A completed hourly candle may still reference an unfinished daily value. Pivot markers may appear on an earlier bar only after later bars confirm the pivot.
• Declare whether positions can span major releases or weekends. Keep that policy fixed instead of removing losing event trades after the test.

Turn the comparison into a small set of rules

Pineify can help express the selected conditions in Pine Script. Use the AI Coding Agent for a written specification, or the Visual Editor for supported indicator and condition combinations. Include the exact feed, timeframe, confirmation timing and exits in the specification. Neither tool establishes that a forex indicator is profitable; that requires a separate, reproducible evaluation.
