For option buyers
Signals for option buyers, with the hard parts left in
Most people who buy options lose money over time, and the main reason is simple. An option loses time value every day, so the buyer has to be right about direction and right about timing. A buy signal on Nifty does not change that arithmetic. It gives you a direction and levels; everything else is still on you.
WizeBuySell plots buy and sell signals with an entry, three targets and a trailing stop-loss. You can run it on the underlying, such as Nifty or Bank Nifty, or on the option contract's own chart. It does not pick the strike, the expiry or the quantity. This page explains how premiums behave around a signal, and what the software leaves out.
Why a correct direction call can still lose money
An option premium is part intrinsic value and part time value. Time value shrinks every day, fastest near expiry, and it rises and falls with implied volatility. So a premium responds to three things at once: where the underlying goes, how long it takes, and how nervous the market is. A signal speaks only to the first.
Take an illustrative case. Nifty is at 25,000 and a buy signal fires with T1 at 25,060. You buy a call. Nifty drifts sideways for three hours, then reaches 25,060 late in the afternoon. The direction was right, yet the call may be barely above what you paid. Three hours of time value has gone and volatility cooled after the morning.
Now the reverse. The same signal reaches T1 within twenty minutes and the premium jumps, because the move came quickly. A futures trader makes the same points in both cases. An option buyer does not.
What the premium tends to do in common situations
General tendencies for a bought option. No figures: they depend on strike, days to expiry and volatility.
| Situation | Premium tends to | What it means for you |
|---|---|---|
| Underlying moves quickly your way | Rise sharply | The case option buying is built for |
| Underlying reaches the target slowly | Rise a little, or not at all | Time decay ate part of the move |
| Underlying goes sideways | Fall steadily | You lose without the stop-loss being hit |
| Underlying moves against you | Fall fast | Exit at the stop-loss; do not average down |
| Volatility drops after an event | Fall even if direction is right | Be wary of buying before an announcement |
| Far OTM strike, moderate move your way | Hardly move | A cheap premium buys a weak response |
Strike, expiry and quantity are your decisions
The software fires on the chart you apply it to. On the Nifty chart the levels are index levels, and you translate them to an option yourself. On the option's own chart the levels are premium levels, but option charts are jumpy, have holes in illiquid strikes and start afresh every expiry. Many users read the signal on the underlying and only execute in the option.
At-the-money and slightly in-the-money options respond most directly to the underlying, and they cost more. Far out-of-the-money options are cheap because they need a large move to be worth anything; on a T1-sized move they hardly react. A cheap premium is not a small risk if you buy many lots of it.
The nearest expiry is cheapest and decays fastest. A later one costs more and gives the move more time. We do not recommend a strike or an expiry. Expiry days and lot sizes get revised, so check the current NSE circular.
Sizing a trade by the premium you can afford to lose
With futures you size from the stop-loss distance. With bought options it is safer to assume the whole premium is at risk.
- 01
Fix the rupee loss per trade
Decide it before the market opens. Keep it small enough that five losses in a row still leave you able to trade next week.
- 02
Treat the premium paid as the amount at risk
Premiums can gap, and a stop-loss order in an option may fill far from its trigger. Plan as if the full premium could go.
- 03
Count lots from the loss limit, not from available margin
Divide your loss limit by the premium for one lot. If the answer is less than one, the trade is too big for your account today.
- 04
Set an exit on the underlying and on the clock
Exit if the underlying hits the signal's stop-loss. Also exit if the move has not started within a time you fixed in advance.
- 05
Log premium in and premium out
Record index levels and premiums together. After twenty trades you will see how often a T1 on the index actually paid you in the option.
Why T1 and T2 matter more to a buyer than T3
The signal gives three targets and trails the stop-loss to entry at T1 and to T1 at T2. A futures trader can sit through a pullback after T1 at no cost except patience. An option buyer pays for that pullback in time value. Every sideways hour between T1 and T3 takes something out of the premium.
That is why many option buyers book most of the position at T1 or T2 and let only a small part run. T3 is reached on trending days, and trending days are not the majority.
What changes on expiry day
On expiry day the remaining time value drains out within one session. Out-of-the-money options head towards zero and can lose most of their value while the index barely moves. At-the-money options swing hard on small index moves, in both directions.
Late-session signals are the hardest, because whatever time value you bought is nearly gone. If you are new to options, watch a few expiry days without a position before you trade one.
This is the highest-risk way to use the software
Buying options on signals combines a tool that is sometimes wrong with an instrument that loses value when nothing happens. Stop-losses get hit. Sideways days produce whipsaws, and each one costs an option buyer more than it costs a futures trader. We publish no accuracy percentage and we make no promise of profit.

Questions about Option buyers
Does the software tell me which strike to buy?
No. It plots direction, entry, three targets and a stop-loss on whatever chart you apply it to. Strike, expiry and number of lots are your decisions. We do not recommend strikes, because we are not SEBI-registered advisers and because the choice depends on your capital, the days left to expiry and volatility that day.
Should I apply the signal to the index chart or the option chart?
Both work, since index options are among the 1,240 symbols covered. The index chart is cleaner, has continuous history and does not start afresh each expiry. An option chart shows premium levels directly but is noisier, and far strikes have thin candles. Try both during the trial.
The signal hit T1 but my option lost money. Why?
Usually time decay, a fall in implied volatility, or a far out-of-the-money strike. If the underlying took hours to reach T1, the time value lost on the way can cancel the gain from direction. The signal is about the underlying's price. It says nothing about how a particular option will respond.
Can I use the signals for option selling?
The signals are directional, so some users apply them to selling, for example treating a buy signal as a cue to sell puts. The software does not model margin, the open-ended loss on a naked short option, or hedges. We give no strategy guidance for selling, and none of this is advice.
Is option buying a sensible way to start with small capital?
It is the most common way and one of the hardest. Small premiums let you take positions that are large for the account, and time decay punishes the hesitation every new trader has. If you are in your first year, consider learning on one stock in cash first.
