Signals and indicators
Whipsaw
A whipsaw is a quick reversal that stops out a trade soon after entry, often followed by an opposite signal that fails as well.
A whipsaw is what happens when price moves enough to trigger a signal and then promptly reverses. You buy, price turns down and hits the stop-loss. A sell signal appears, you sell, and price turns back up. The name comes from a two-handled saw pulled back and forth. Each cut is small, but several in a row add up.
Whipsaws belong to sideways markets. Any method that follows trend, including moving average crossovers and most buy and sell signal tools, needs price to keep going after the signal. In a narrow range it does not keep going. It oscillates around the same area, and every small swing looks for a moment like the start of a move.
Indian intraday traders meet them most in the midday lull, when Nifty can sit in a tight band for hours. They also appear ahead of a major event, when large participants wait. Very low timeframes such as 1-minute produce more of them than 15-minute charts, because noise is a bigger share of each candle.
The common mistake is to respond by adding filters until the last whipsaw would have been avoided; the next one will be different. The other is taking every signal in a plainly flat market. Practical defences are simple: step up a timeframe, stand aside when the range is unusually narrow, and cap the number of trades you take in a day.
Worked example
Two whipsaws in a flat Nifty session
Illustrative numbers: on a 5-minute chart Nifty stays between 24,980 and 25,020 from 11:30 am to 1:30 pm. A buy signal comes at 25,015 with a stop-loss at 24,985; price drops and the stop-loss is hit for minus 30 points. A sell signal follows at 24,985 with a stop-loss at 25,015; price rises and that is hit too, another minus 30. The total is minus 60 points plus costs on two trades, while the index has gone nowhere.
In WizeBuySell
WizeBuySell reads price, and like any signal method that depends on follow-through it will give whipsaws in a sideways market. We say so plainly. The stop-loss on each signal defines the loss on each one, and candle-close confirmation removes some mid-candle noise, but neither makes a flat market tradable. Choosing a higher timeframe, or not trading a dead session, is a decision only you can make.
