Why TickAtlas

What is the DeMarker API?

The DeMarker indicator, created by Tom DeMark, compares recent high and low prices to prior highs and lows to identify price exhaustion points. Unlike RSI which uses closes, DeMarker focuses on intrabar extremes — making it more sensitive to short-term price reversals. Values oscillate between 0 and 1. Our API delivers pre-calculated DeMarker(14) so your trading bot can trigger on overbought/oversold extremes without any calculation overhead.

Pre-Calculated, Redis-Cached

Indicator values are computed server-side on every new candle. Your app queries the result — no TA library, no candle history needed.

Frequently asked questions

What developers ask first.

Straight answers on limits, coverage and how the endpoint behaves in production.

How does DeMarker differ from RSI?

RSI uses closing prices to measure momentum. DeMarker compares the current period's high against the previous high (DeMax) and current low against previous low (DeMin). This focus on intrabar extremes makes DeMarker more responsive to reversal setups forming within a candle.

What do the 0.3 and 0.7 thresholds mean?

Below 0.3 indicates the market has been making lower lows relative to previous lows — oversold conditions where buyers may step in. Above 0.7 indicates consistently higher highs — overbought conditions where sellers may take over. The API returns these signals pre-classified.

Is this useful for Forex specifically?

Yes. DeMarker was designed with Forex in mind by Tom DeMark. It works particularly well on currency pairs where intraday reversal timing is critical for scalping and day trading strategies.

Can I use DeMarker with an AI agent?

Yes. Feed the DeMarker value into a ChatGPT Custom GPT or Claude Tool to get conversational market analysis. The bounded 0–1 range makes it easy for AI models to reason about market conditions.
