Wholesale Prices

Wholesale prices refer to the prices retailers pay when buying finished goods in bulk from producers or distributors before selling them to consumers at a markup. Because they reflect costs earlier in the supply chain, they are often watched as an early signal of inflation. If wholesale prices rise, consumer prices may follow.

A common measure of wholesale inflation is the Wholesale Price Index (WPI)—called the Producer Price Index (PPI) in the U.S. It tracks changes in wholesale prices over time and helps economists gauge inflationary pressure.

Example:

If a retailer buys coffee makers from a wholesaler for $40 each and sells them in-store for $65, then $40 is the wholesale price. If the wholesaler raises the price to $45 because of higher import costs, that may later lead to higher retail prices.

Wholesale prices can rise due to supply disruptions, tariffs, rising input costs, or geopolitical tensions. In financial markets, traders monitor wholesale price data because stronger-than-expected increases may influence inflation expectations, interest rates, and currency movements.

In short, wholesale prices offer an early look at cost pressures building in the economy before they reach consumers.

Wide bid-ask spread

The difference between the highest price a buyer is willing to pay for a product and the lowest price a seller is willing to accept.

Wildcard option

An option that can be exercised at any time during its lifetime.

Williams %R

Williams %R is a technical indicator that helps traders see whether an asset may be overbought or oversold. In simple terms, it compares the latest closing price with the highest and lowest prices over a chosen period, usually 14 days.

The indicator moves between 0 and -100. A reading above -20 often suggests the asset may be overbought, meaning the price is near the top of its recent range. A reading below -80 often suggests it may be oversold, meaning the price is near the bottom of its recent range.

Traders use Williams %R to look for possible entry and exit points. However, it should not be used alone, because strong trends can keep the indicator overbought or oversold for a long time.

Example:

If a stock trades between $40 and $50 over 14 days and closes near $49, Williams %R may move above -20. This suggests the stock is near the top of its recent range, so traders may watch for a possible pullback.

In short, Williams %R helps traders read short-term momentum.

Win Rate

Win rate is the percentage of trades that end in profit compared to your total number of trades. It helps traders measure how often their strategy is successful.

The formula is simple:

Win Rate = (Winning Trades ÷ Total Trades) × 100

For example, if you take 50 trades and 30 are profitable, your win rate is 60%.

A higher win rate may suggest consistency, but it does not automatically mean a strategy is profitable. What matters is how win rate works together with risk-reward ratio. A trader with a 40% win rate can still be profitable if winning trades are much larger than losing ones.

For example:

Trader A wins 70% of trades but makes small profits and takes large losses.

Trader B wins only 45% of trades but each winning trade makes three times more than each loss.

Trader B may be more profitable.

Traders use win rate to evaluate strategy performance, improve risk management, and measure consistency over time. But it should always be viewed alongside factors like average profit, average loss, and market conditions.

In short, win rate tells you how often you are right — not how profitable you are.
