What a study looks like in the app
-
1 What it read
Levels from your chart. A real study checks them against 300 bars of real prices.
-
2 Both cases
What would strengthen each case, and the close that would invalidate it.
-
3 How it was made
Every point says where it came from. Gaps are listed, not guessed.
The app's own sample study. Example, not a live analysis.
See what goes into a study.
Every point shows where it came from: your chart, real price data, or a calculation.
BTC/USD · 1D
Illustrative sample · not real or live market data · last 120 of 300 daily bars
- Resistance
- Support
- Prior higher low
RSI(14)
-
- Contact points
- 71,380, 71,400, 71,350 (bars 13, 63, 105 of 120 shown)
- Interpreted level
- 71,400, the mean of those highs to the nearest 100
- What this is
- An observation read from the image. It is interpretation until it is checked.
-
- Instrument
- BTC/USD, daily bars, aligned to the chart's own period.
- Swing lows
- 63,948 (bar 40), then 66,442 (bar 84)
- Window
- 300 bars ending at the chart's last candle.
- How it was checked
- Each swing low in the reading is matched to a pivot low in the price series: a bar lower than the three on either side.
- Provider
- None for this sample, whose bars are illustrative. A real study names its provider and venue here.
-
- Period
- 14 bars
- Input
- Daily closes, the same 300 bars as the check.
- Method
- Wilder-smoothed average gain over average loss.
- Result
- 46.4 at the last close. Between 40 and 60 reads as mixed.
-
- What's missing
- The screenshot's volume pane has no scale, so the bars show a fall but not its size.
- Historical volume
- Not part of this sample's data, so it can't settle the question either.
- Effect
- A real contraction would usually strengthen a range like this. The study notes the fall and leaves its size open instead of assuming it.
Bullish and bearish scenarios
The same evidence, read both ways. Each case says what would strengthen it and the close that would invalidate it.
Bullish case
- What the chart shows
- Price is in a range under 71,400, a level it has touched three times. The lows inside the range are rising: 63,948, then 66,442.
- Would strengthen it
- A daily close above 71,400.
- Invalidated if
- A close back below 71,400 after a breakout, or a close below 63,900 that breaks the rising lows.
Bearish case
- What the chart shows
- Range support at 66,400 has held so far. RSI(14) is 46.4, just under the midline, so momentum is mixed.
- Would strengthen it
- A daily close below 66,400.
- Invalidated if
- A close back above 66,400, or a close above 71,400.
Levels come from this illustrative sample. Neither case is a prediction.
From chart to study in three steps.
-
Step 1
Send a chart
Upload a screenshot from any charting app, or pick a stock or crypto symbol and timeframe.
-
Step 2
It's checked
What it reads is compared with 300 bars of historical prices for the same symbol and timeframe. Indicators are calculated from those prices, not guessed from the image.
-
Step 3
Read the study
Key levels, bullish and bearish scenarios, the source behind each point, and what is still uncertain.
A study doesn't end when you close the chart.
Save your research, revisit the scenarios, and see which levels price actually crossed. Build a history of evidence you can learn from.
- Your journal
Every finished study is saved until you delete it, with favourites to keep the ones you come back to.
- What happened next
A study matched to real prices is followed for its next 20 bars. It records which of its two levels price closed beyond first, and when, or that price stayed between them.
- How your studies played out
Counts across your own followed studies, so you can look back at how your readings and the market compared.
A close beyond a level records a price event. It is not a grade of the study, a forecast, or a trade result. How outcomes are recorded
When it can't tell, it says so.
Some screenshots are incomplete, and some charts don't support a clear reading. Blockstudy labels those gaps instead of guessing.
- Unreadable screenshot
Unreadable charts are rejected without using a study.
- Unverified observation
A point it can't confirm against historical prices stays labelled unverified.
- Conflicting evidence
When the evidence points both ways, the study explains the disagreement.
