For you, Chavitravi:
The short answer: because “more sells than buys” on sites like ADVFN or LSE does not actually mean more people were selling than buying, and the reported buy/sell split often has no direct relationship to price direction.

Why the price can rise even when reported “sells” outnumber “buys”
1. Buy/sell labels on ADVFN & LSE are guesses, not real data
Platforms such as ADVFN and London South East do not know whether a trade was initiated by a buyer or a seller.
They infer it using the bid–ask midpoint:
• Trades near the bid are labelled “sell”
• Trades near the ask are labelled “buy”
This method is not reliable, especially in AIM stocks with wide spreads and low liquidity.
So a large portion of the “sells” you saw may actually have been buys.
This is a well‑known limitation of UK retail trade reporting (inference based on bid/ask, not actual order flow).

2. Price moves are driven by the aggressor, not the label
A trade only moves the price if the aggressor (the side crossing the spread) lifts the ask or hits the bid.
If buyers are aggressive and repeatedly lift the ask, the price rises —
even if the system mislabels those trades as “sells.”
---
3. Market makers can raise prices even on low buy volume
Helix Exploration trades on AIM, where market makers control the quotes.
Market makers may raise prices when:
• They anticipate demand
• They are short of inventory
• They see institutional or delayed trades coming
• News flow is positive (e.g., helium sales arrangements, drilling updates)
This can push the price up without visible buy volume.
---
4. Delayed trade reporting can distort the picture
Some trades qualify for deferred publication due to size or type.
These appear later, often at prices that make earlier volume look like “sells” even though they were part of a larger buy program.
This is explicitly noted in LSE trade reporting rules.
---
5. AIM stocks often move on sentiment, not volume
Helix has had:
• Helium sales agreements
• Positive drilling updates
• Institutional interest
• Strategic partnerships (e.g., USAF‑related selection)
Even modest buying pressure can move the price sharply because the free float is relatively small and liquidity is thin.
---
Putting it together for today’s situation
If ADVFN/LSE shows 4.5× more “sells” than “buys” but the price rose, the most likely explanation is:
Most of those “sells” were actually buys misclassified by the bid/ask algorithm, and the real order flow was dominated by buyers lifting the ask.
