How to read the evidence card
The evidence card shows the chart counterpart of every claim the analysis makes: trend, momentum, levels and volatility can be switched on and off one by one as layers.
BBL analyses do not just say ‘buy’ or ‘wait’; they also show which evidence the decision rests on. We call the chart version of that evidence the evidence card. The chart above is a small evidence card example.
You see four kinds of evidence on the chart. The orange, light grey and dark grey lines are the 20, 50 and 200-candle averages; their order describes the trend. In the RSI panel below there is a coloured band and a dot at the right end; this is momentum, that is, whether rises or falls are stronger. The horizontal lines labelled ‘SUPPORT’ and ‘RESISTANCE’ on the left edge are levels. The band framed by yellow dashed lines is ATR, price's normal range of movement.
In a real analysis the evidence card can hold much more: patterns, divergences, volume zones, order blocks. When you tap the chips under the card, you focus on that evidence: the others fade and what you selected is explained. A long press or right-click hides the layer. The ‘Replay’ button redraws the evidence in order.
The real purpose of the card is not to teach you to trust but to verify: if the analysis says ‘there is a double bottom’, you should be able to see that double bottom on the chart. If you do not, the question to ask is: what is this claim based on?
The evidence does not always point the same way. The trend may be up, momentum weak, and price just below a resistance. These contradictions are not an error but the real state of the market; in such cases the analysis usually makes a more cautious decision. Seeing the conflicting evidence on the card is the shortest way to understand why decisions like ‘wait’ or ‘in stages’ are given.
How to read it
- Read the trend first: the order of the averages and price's position relative to them give the big picture.
- Then read momentum: which zone is RSI in, and does it agree with the trend?
- Evaluate the levels and the ATR band together: see what the stop and target levels rest on in the chart.
- Match every claim in the analysis text with a chip on the card: a claim without a match is a claim without evidence.
We measured
We ran an audit that re-measured what the evidence card draws using raw price data: 45 cases in total across 6 crypto pairs and 5 BIST stocks on different time frames. Every layer was recalculated from scratch without trusting the system's own claim. The audit uncovered some real bugs; for example, on BIST daily charts the card was not drawn at all because of a missing last candle. After the bugs were fixed, the follow-up audit found no critical errors and no drawing violations.

Trap
The most common mistake is treating the evidence card as decoration and looking only at the result badge. The badge is a summary; the same ‘BUY’ badge can come from a setup supported by a strong trend or from a single weak piece of evidence. The second mistake is ignoring grey (invalidated) layers: why the system dropped a thesis is as instructive as why it kept one.
Tip
In your next analysis, look at the evidence card before the badge and ask yourself: ‘Had I seen this chart, would I have reached the same conclusion?’ Over time this habit teaches you to think together with the system rather than follow it blindly.
