Time-weighted average price. More reliable than VWAP for thinly-traded cards with big gaps between sales.
Kalman Filter PRO
Adaptive noise filter. Smooths erratic price data to reveal the true underlying trend — ideal for low-liquidity cards.
Fibonacci PRO
Key levels from the high/low range. Green lines = retracement support. Orange lines = upside extension targets.
f Ratio PRO
Custom grade ratio (e.g. psa10/raw). Charts the price gap between two grades over time — useful for spotting when grading premium is unusually high or low.
DTL PRO
Days to Liquidation. Current eBay listings ÷ average daily sales. A high DTL means the market is saturated and it may take a while to sell.
BB Squeeze PRO
Shades the chart when Bollinger Bands tighten below their normal range — a sign the card is consolidating after a move. Tight bands often precede a breakout in either direction. Only fires after a period of wider bands, so quiet cards that have always been calm don't trigger it.
Signals PRO
Buy (▲) and sell (▼) markers that only appear when 3 or more indicators agree at once — BB band reversal, RSI crossing out of overbought/oversold, MACD histogram flip, MA20 crossover, and/or volume spike. A single indicator alone never fires a signal; it needs multi-factor confluence to keep false positives low.
MAD Band PRO
Median Absolute Deviation band — a robust price range envelope built on the rolling median rather than the mean. Unlike Bollinger Bands it isn't skewed by a single outlier sale, making it the most reliable volatility indicator for cards with very few transactions. Price trading outside the band signals unusual activity worth watching.

When Does the Data Work?
CardChart pulls daily eBay sold prices from PokeTrace. Technical analysis is only as good as the underlying data — here's when it's reliable and when to treat it with caution.
✅
Works well: Modern sets (2019+), popular chase cards (Alt Art, Full Art, Gold Rare), Raw NM condition, PSA 10 on high-demand cards. Look for 30+ data points and volume bars that are consistently non-zero.
⚠️
Use with caution: Cards with fewer than 15 data points, cards that sell only a few times per month, brand-new sets with less than 3 weeks of history.
❌
TA is unreliable: Hyper-rare vintage cards (Base Set Shadowless, 1st Edition), ultra-low-population graded slabs, cards with large price swings caused by a single auction.
💡
Best starting point: Raw NM has the most sales volume of any condition. Start there to learn the chart before switching to graded tiers.
Reading the Chart
Each candle represents one day of eBay sales data sourced from PokeTrace.
Open / Close
Open = the previous day's closing price. Close = the average of all sales recorded that day. A green candle means the average sale price rose; red means it fell.
High / Low (Wicks)
The wicks show PokeTrace's recorded max and min sale price for the day — the best and worst deals transacted. Wide wicks mean high price variance across buyers that day.
Volume Bars
Height = number of transactions recorded. Green = up day, red = down day. High volume confirms a price move; a spike on low volume is often noise or a single outlier sale.
Gaps in the Chart
A missing candle means zero eBay sales were recorded by PokeTrace that day. Common on low-demand cards and weekdays for niche sets. MA lines carry forward through gaps.
Timeframe
7D is too short for any meaningful pattern. 1M shows recent momentum. 3M–6M is the sweet spot for support/resistance. 1Y gives you the full cycle view.
Chart Patterns
These are the most common price structures you'll see in the Pokémon card market. Each one has a specific meaning for supply and demand.
Support & Resistance
Support is a price floor the card keeps bouncing off — lots of buyers step in around that level. Resistance is a ceiling it can't break through — sellers keep offloading near that price.
For cards: Support often forms at round numbers ($50, $100). Resistance forms at all-time highs or near PSA pop-report milestones.
Breakout
Price closes decisively above a resistance level, usually on higher-than-normal volume. The prior resistance often becomes new support after a confirmed breakout.
Watch the volume bar — a breakout on low volume is a false signal. Viral social posts and tournament results drive most card breakouts.
Consolidation (Flag)
After a big move, price trades sideways in a tight range for several weeks. Volume shrinks. This is the market "digesting" the move — it often precedes another leg in the same direction.
Very common in Pokémon after a hype cycle. The flag pattern after a hype run often resolves downward once the social buzz fades.
V-Bottom
A sharp drop followed by an equally sharp recovery, forming a V shape. Usually caused by a temporary oversupply — a bulk PSA return hitting eBay at once — followed by renewed demand.
If the V-bottom holds above prior support, it's often a strong buy signal. If it reclaims the prior level fast, the dip was a one-time supply event.
Rounding Top
A slow, gradual price rise with declining volume as it peaks, then a slow rollover. Sellers are quietly unloading into rising demand until buyers run out. Bearish signal.
Common at the peak of a card's hype cycle. By the time it's rounding, most of the upside is already priced in.
Indicators Explained
All indicators are calculated from real PokeTrace sales data. Pro indicators are marked ★.
Bollinger Bands
A volatility envelope around price. When bands are tight, the card is in a calm period — often before a breakout. Price touching the upper band in an uptrend is bullish, not automatically overbought.
MA20 / MA50
Moving averages smooth out daily noise. MA20 above MA50 = short-term bullish. MA20 crossing below MA50 (death cross) = bearish momentum building. Price bouncing off MA20 during a trend = healthy.
Volume
High volume confirms a price move. A large candle on low volume is suspect. Declining volume on pullbacks during an uptrend = buyers still in control.
RSI ★
0–100 scale. Above 70 = potentially overbought (consider waiting to buy). Below 30 = potentially oversold (possible bounce). On low-volume cards, a single large sale can push RSI to extremes without meaning.
Volume-weighted average price — the "fair value" weighted by how many cards actually sold at each price. Price above VWAP = buyers in control. Below = sellers in control. Most useful on cards with consistent daily volume.
TWAP ★
Time-weighted average — gives more weight to prices that persisted longer between sales. Useful for cards that sell infrequently; it smooths out the effect of long gaps between transactions.
Kalman Filter ★
A signal-processing filter that estimates the "true" price trend by separating signal from noise. More responsive after data gaps. Best on sparse cards where standard MAs lag badly.
BB Squeeze ★
Highlights chart regions where Bollinger Bands have tightened to their narrowest in a while — a sign the card's price is consolidating after a move. Tight bands mean low volatility and coiled energy. The shaded zone often precedes a breakout. Only fires after a wider period, so quiet cards that are always calm don't trigger it.
Signals ★
Buy (▲) and sell (▼) markers that appear only when multiple indicators agree at the same bar. Each signal scores: BB band reversal (+2), RSI crossing out of overbought/oversold (+2), MACD histogram flip (+2), MA20 crossover (+1), volume spike (+1). A signal only fires at score ≥ 5 — meaning at least two strong factors must align. Lone crossovers never trigger it.
MAD Band ★
Median Absolute Deviation band — a volatility envelope around the rolling median. Unlike Bollinger Bands, it uses the median (not mean) and measures spread via median-of-deviations, so a single outlier sale can't inflate the band. Works reliably with as few as 3 data points, making it the best volatility indicator for cards that trade only a few times a month. Price outside the band = unusual activity worth watching.
