Why Volume Tells You More Than Price
A high rate on thin arrivals is a quote, not a market. Knowing whether you can actually sell into a price is a different question from knowing the price.
Prices are easy to find and easy to repeat. A trader hears that a market touched a good rate yesterday, and the number lodges. What almost never travels with it is how much actually changed hands at that rate — whether it was the clearing price for a day of heavy arrivals, or the figure paid for two lots that happened to be the only good ones available.
Those are entirely different pieces of information wearing the same clothes. The first tells you what a market will absorb. The second tells you what one buyer paid on a thin day, and it will not survive your consignment arriving.
The missing variable is arrivals — how much came to market. Read alongside price, it changes what the price means.
Reading the two together
High price, low arrivals
Scarcity. The rate is real but shallow: it reflects competition for a small quantity. A large consignment arriving into this market does not get that rate — it becomes the supply that ends it. The most common way sellers are disappointed by a price they were confident about.
Moderate price, heavy arrivals
Depth. The market is absorbing volume at this level, which means your consignment can probably be sold near it. Less exciting to hear about and far more reliable to act on.
Falling price, rising arrivals
Supply building. Usually the start of a trend rather than a single day’s movement, and a signal to sell sooner rather than to wait for a recovery that the arrival pattern does not support.
Rising price, rising arrivals
Genuine demand. The strongest of the four signals, because the market is taking more volume and paying more for it. Rare, and worth acting on when it appears.
Why a thin-market price does not survive contact
| Situation | Quoted rate | What a large lot realises |
|---|---|---|
| Thin arrivals, few good lots | ₹1,400 | Substantially below the quote |
| Steady arrivals, active buying | ₹1,250 | Close to the quote |
| Heavy arrivals, buyers selective | ₹1,100 | At or slightly below the quote |
Illustrative characterisation of how market depth affects realisation. These are not observed rates and the outcomes are directional, not measured.
The rate you were told about was set by the absence of supply. Your consignment is supply.
Using this before you dispatch
Ask what arrived, not just what it fetched. If you can only find the price, treat it as a weaker signal than you would like it to be.
Size your expectation to your consignment. A rate achieved on a small lot is not available to a large one. The bigger your consignment, the more depth matters relative to price.
Watch the direction of both together. Price and arrivals moving the same way tells you something real. Price moving without arrivals moving usually does not.
Prefer a market you can sell into. A slightly lower rate in a market that reliably absorbs volume beats a higher rate you cannot actually access.
Arrivals information is harder to come by than price information, which is precisely why price gets over-weighted in these decisions. Platforms such as Potato Bazaar collect mandi information across markets, including reported arrivals where the market publishes them. It is worth being clear about what that is and is not: this is market-reported arrival and price information, not a record of transactions concluded on the platform, and coverage varies by market. Used with that understanding, it gives you the second variable this article is about. Used as though it were complete transaction data, it would mislead you.

See price alongside arrivals
Look at what markets are reporting for both, so a rate can be read in context.
The short version
A price without a volume is half a fact. Before dispatching, ask what arrived alongside what it fetched — and size your expectation to your own consignment, because a rate set by scarcity ends when supply appears.
Why is a high price sometimes a bad signal?
Because it may reflect scarcity rather than demand. When few lots arrive, competition for them can produce a strong rate that applies only to that small quantity. A large consignment arriving afterwards becomes the supply that ends the scarcity, and does not achieve the same rate.
What are arrivals and why do they matter?
Arrivals are the quantity coming to a market in a given period. Read alongside price, they indicate depth — whether the market is absorbing volume at that level or whether the rate applies to a handful of lots. Price alone cannot distinguish between those two situations.
What is the strongest combination to look for?
Rising price with rising arrivals. That combination indicates genuine demand, because the market is taking more volume and paying more for it at the same time. It is the least common of the four patterns and the most worth acting on.
Does consignment size change how I should read this?
Yes, considerably. A small lot can often achieve a thin-market rate because it does not materially change supply. The larger your consignment, the more the depth of the market matters relative to the headline price, because your own arrival affects the balance.
Is arrivals data the same as transaction data?
No. Arrivals are what market sources report as having come to market, which is different from a complete record of transactions and their prices. Coverage varies between markets. It is a useful second variable alongside price, not a comprehensive account of what was traded.
