Use these calculators to identify traditional pivot levels, plan position size and risk, and map potential Fibonacci levels. Enter your own numbers, review the assumptions, and use the results as part of a complete trading plan.
Calculate traditional support and resistance reference levels using the previous period's high, low, and closing prices.
The Pivot Point is the central reference level calculated from the prior period. R1 through R3 are progressively higher reference levels, while S1 through S3 are progressively lower reference levels. Traders may watch how price behaves near these areas, but the levels should not be treated as automatic entries, exits, or predictions.
At Alphatrends, we look to take a partial profit if the stock reached R2 on the day of entry, this is merely a method to reduce overall risk. For short sales we use the same technique at S2, only on the day of entry.
Calculator note: Pivot formulas provide reference levels only. Always consider current market structure, trend, volume, and risk.
Estimate how many shares fit your risk limit before entering a trade.
The trade does not fit the risk and capital limits entered.
Position size is determined by the distance between the entry and stop, the amount you are willing to risk, and the capital available for the trade. A wider stop generally results in fewer shares. A tighter stop generally results in more shares, but the stop should still be based on the trade's price structure—not chosen simply to increase position size.
Calculator note: This tool provides a stock-share estimate and does not account for margin requirements, borrowing costs, options contracts, partial fills, taxes, or broker-specific rules.
The optimal position size will vary for each individual, it is not meant as a one size fits all. Only you know what the appropriate risk is for your individual circumstances.

Price-level illustration
Spacing reflects the calculated prices in the table above. Lines marked with a dot and shown in orange are the most commonly watched levels. This illustration is not a live chart and does not indicate which level will hold.
Fibonacci levels divide a measured price move into commonly monitored proportions. Retracement levels identify prices within the original move. Extension levels project prices beyond a pullback or countertrend bounce. These are mathematical reference points—not proof that price will reverse, stop, or reach a particular level.
These are mathematical reference points or "levels of interest", not proof.
Calculator note: The usefulness of any Fibonacci level depends on where the move is measured. Use clear swing points and consider trend, market structure, volume, and risk.
A calculation can help organize a trade, but it cannot determine whether a setup is valid. Before acting, consider where price has come from, the broader trend, nearby support and resistance, liquidity, and the amount you can afford to lose. Plan the trade before entering it, then remain disciplined enough to follow that plan.
