1. Can i use any ratio other than 1:1 for my diagonal spread? How will it affect the performance of my diagonal spread?

e.g. say my desired hedge is 35% and say my preferred spread is ATM long and 2nd OTM short but this spread is not providing the desired hedge. Instead of shifting to ITM or OTM long, can i ratio my preferred spread such as to obtain desired hedge?



One could surely do something like this provided one is really comfortable trading options. Taking on more short options than long is certainly riskier and turns it into a completely different trade with different P/L scenario. So it has to be analyzed in a different way altogether.

Ratios ideally must be traded when implied volatility of options is significantly higher than usual. If you have access to IV charts then you can time such positions properly or you could just use VIX to time it. Trading something like this when volatility is low can be difficult as sudden increase in volatility can be quite damaging to the ratio. Eg. VIX went from around 13 (Dec end) to around 19 at the moment. This may have been a major drag for a ratio.

So a ratio must be initiated with proper thought.

2. Can i use delta of the spread as measure of hedge?

I believe you use "short option price/long option price" as measure of hedge as you wish to compare performance of spread vis-a-vis naked long option. But most of us trade normally in futures and hence comparing the spread performance vis-a-vis naked futures will give us a better idea. For this reason, can we use delta of the spread as measure of hedge. What delta value should we look for to obtain reasonable hedge?



Sure, I have used option premium to compute hedge just for convenience. If you have access to delta, you certainly can use that. Depending on how much hedge you require you could select the long & short deltas. As I suggest you should use ITM option for long, a delta of around 0.60 is good for long. A 0.30 delta would probably good for short option. This is my suggestion, will need to check more...

I have downloaded options oracle (compatible with NSE) for IV charts and greeks but not sure if the inputs they have used (interest rates, etc) match with our markets. What is your experience with options oracle? Can we use the greeks values calculated by it for our trading?

I had used it quite a while ago. The greeks seemed fine to me at that time. I had removed the software as it had stopped working for NSE. I see that a version of it provided by someone works for NSE now. Check and see if there is a way to change interest rate etc. I think there should be some way to do it, in the settings maybe. I don't remember if it is there.

I will see if I can install and take a look at it. Will let you know after I take a look.

Thanks for your reply ST.

I have downloaded version 1.60 provided online by a guy called Pasi. In configuration settings, it has option to enter federal interest rate which i guess is the one that will be used to calculate greeks. By default the value is 0%. I have changed it to 10% as NSE uses 10% as interest rate for calculating IV. Should we use 10% or some actual rate like the RBI prime lending rate or base rates provided by various banks for more accurate calculations?

I suggest you use 1 month MIBOR rate. It is available here : https://www.ccilindia.com/Research/Statistics/Pages/FIMMDA_CCIL_Term_Rates.aspx

Dear ST,

First of all, thanks a lot for all your guidance.

I have been backtesting diagonal spreads for past few years data. What i have noticed is that the far month is quite illiquid in most of the cases. If your entry signal comes within 2 weeks from 1M expiry, you have to take long in 3M and short in 2M and in such cases this lack of volume hurts you. The volumes are too less to get you a fill at the desired price.

I was researching on finding a good solution to this. One alternative that comes to my mind is instead of going long in 3M option, we can trade the 2M future and short the 2M option. The position can be taken in a ratio such that the delta of this position matches the delta of the original diagonal spread.

The advantage is that volumes in 2M futures are much higher, while the flip side is that margin required is almost 3-4 times. But, if you had not planned to leverage your diagonal to the hilt, then you won't mind the increased margin.

What I would like to know from you is that, in what ways the payoff of such a trade differ from that of a diagonal spread.

Thanks in advance.

Dear Friends ..

Positive cross over 13 x 89 on 60 min. chart ... also closed above cross over candle high. Is it considered valid or have to wait for 13 x 233 crossover too ?

This becomes a completely different trade once futures are used in place of long option. I have not tested this in detail so I can't comment on it more. The way to manage it would also be very different. Usually if I don't see liquidity in the next month option then I just trade a vertical instead of diagonal. The process of monitoring / managing it remains more or less the same.

Chirag Ji,

The trend is strongly down so I would wait to see what happens at the 13/233 crossover point. But this is just a suggestion. If you are willing to exit and reverse the trade or adjust quickly then you could take a chance of initiating a bullish trade at this point. But do keep watching for a reversal down.

TRADE ADJUSTMENTS

There was a bullish crossover of 13/233 EMA around Dec end. If one had taken a bullish trade around that time then the trade turned out to be a losing one. So how could one have adjusted the trade to turn it into a smaller loser or maybe even a winner?

Here are some ideas on diagonal trade adjustments. Please do note that I am giving one idea that is low risk and the other is high risk. Please understand the risk and only then make adjustments using these ideas.

1. Rolldown the short option

This has been mentioned before. Short option can be rolled down multiple times as price keeps going down (and short option loses most of its premium). The idea is to recover as much cost of long option as possible as long as price keeps going the other way (down in this case).

As we keep rolling down the short option, the trade goes from two strike wide diagonal to one strike wide, then a calendar spread and then a one strike wide bearish call diagonal and then to a two strike wide bearish call diagonal. One should not go further than this as it will increase the risk significantly. Also, try and make sure the short strike is at least around two strikes above the current NF price.

2. Convert to ratio and rolldown

This is risky as we will have one naked option short. This adjustment must be done ONLY if you understand the risks and are prepared to adjust trade further quickly if price moves against you.

To do this, roll down the short option one strike down (to make the spread one strike wide) but short two contracts instead of the one. The idea is to recover the cost of long option quicker if price continues down. If price moves back up then you have breathing space only until the short strike and you must adjust quickly (roll up the short again and remove the extra short).

The roll down of two shorts can continue until the spread turns into a bearish ratio spread that is two strikes wide. It is suggested that one stop at this point as a spread wider than this would be risky if there is a price reversal up. Do note that always keep a good gap between NF price and the short strike when adjusting.

For the Dec trade (Jan expiry), if one had initiated a bullish spread then the first adjustment would have resulted in a smaller loser after adjustments and the second adjustment would have turned the trade into a profitable one (but at a greater risk).

Which adjustment to choose depends on the trader based on his risk appetite.

I had taken the bullish crossover trade of Dec end, by entering in a Bull Call spread (7800c Feb Long and 8000c Jan short). However, on bearish cross at Jan beginning, I simply got out of this bullish diagonal at a small loss AND took the Bear Put spread (7800p Feb Long and 7600p Jan short) which went off very well. Had there been another reversal, I would have again reversed by liquidating bear put spread and entering the bull call spread. On some earlier occasions, I did try this adjustment method, without much success. We do not know how far the market is going to go after each crossover, in which trade to make adjustment, and which one to square-off. Simpler thing is to flow with the trend, whatever method for trend one follows.

My take on adjustments is that when we start making adjustments on seeing reversal on charts, we are simply not accepting the fact of reversal and entering into defending the original position, entering into a fighting mentality. This mentality impacts other trades also. That said, every trader has to formulate strategy, which best suits his/her personality.

Very well put. I should also have made this clear. Adjustments make sense only until our trend direction bias is still to the upside (in the above example). If trend direction bias changes then there is no sense staying with the position and adjusting further.

The idea I was trying to convey is that, for eg., entering a 7900c-8000c bull spread and later adjusting it and converting it to 7900c-7700c bear spread is like entering into a bearish trade anyway. But yes, instead of slowly adjusting it step by step, it would be better to convert a bull spread into a bear spread if our trend bias changes. Either that or as you mentioned exit and enter a put bear spread. But I do trade the above often (converting the bull spread to bear spread keeping the long option intact).
