....and also curve fitting (so many system traders have "re-fitted" their index filters this year ??).
Skate, what MA period are you using now for your index filter?
Good afternoon Skate@DaveTrade, coding a system with half-decent returns with a low drawdown is hard to achieve. There is a lot of mathematical gymnastics involved to achieve this.
Skate.
@ducati916 falsifiability is a word I haven't come across before, I had to look up the definition, and yes I think my statement would be falsifiability but I was making a statement as @Skate described. Thinking further on Drawdown between Discretionary & Mechanical systems I'm now wondering if there may be a difference not based on the type of system but on the type of structural money management that is employed. Money management will have an extra layer of complexity for me as I'm planning on using options to trade this system. If you have thought about this aspect of systems I would appreciate your feedback.
I have previously posted in this thread about a weekly system that I want to start trading in the future. The type of system that I want is relative conservative with the focus on minimizing the drawdown of the system. With this in mind I've drafted the potential money management for this system and I'd like feedback from all who wish to give it, don't hold back, give me the good and the bad. I thought that I may as well take advantage of being a member of this forum and draw on the experience and the diversity of the viewpoints of it's members. The way I see it is that any other opinions on this can only help me end up with a better money management system.
First draft of a plan to manage system risk
Maximum 10% of a/c allocated to each trade; e.g. a/c $100,000 would be $10,000 per trade. Therefore the number of options purchased for each trade will be equal to ‘$10,000’ divided by the ‘Option Premium’
Potential maximum number of trades would be 100000/10000 = 10. If this is halved to a maximum of 5 trades then the maximum amount of the a/c in the market at one time would be 50%. A 50% reduction in a/c risk.
If the initial stop-loss for each trade is 25% of the premium then amount at risk on each trade would be 10000/4 = $2,500. This would mean that 2500 x 5 = $12,500 would be the max risk on all 5 trades. This means that 12500x100/100000 = 12.5% of the total a/c would be at risk at any one time. This would be the percentage a/c loss if all 5 trades in the market were stopped out for a maximum loss at the same time.
Yes I use Options combined with a stock position. There are however a number of ways to structure this: Futures/Options, Options/Options or Stock/Options.
I use them in a way that market direction is not a variable. Up or down, you show a profit. The risk is going sideways for an extended period of time, although a trading range is fine and very profitable.
Decisions that you need to pay attention to in setting up any new position:
(i) Duration (Expiry),
(ii) ITM, ATM or OTM,
(iii) IV/HV
(iv) Rebalancing timeframe (more based on commissions than anything else).
Once you have set up the trade correctly (or your best estimation) you have a guaranteed max. loss (barring total loss if the brokerage implodes or the market closes, but that is another topic) and an unlimited upside/downside (downside is limited to 100% x leverage so still high).
This is stress free trading. I'm indifferent to market direction. All rebalancing is simply a calculation based on Black Scholes Model.

Good afternoon Skate
Yes that is true.
There are some trading constructs that opt out of drawdown methodologies. Best explained in this manner:
An economic cycle:
recovery and subsequent expansion;
the peak ...
contraction and subsequent recession ...;
and trough.
Peak to peak!!!
Some fast traders tend to stick with the top two, certainly never the 4th. That would be an abstract failure. rcw1 will not entertain the 3rd one either. That too is a trader's failure and skill tester, a long hard road towards perfection ha ha ha ha ha.
Kind regards

One of my favourite thought bubbles. There will be periods when a discretionary input beats the mechanical system. Unfortunately there'll also be periods when the discretionary input provides worse results that the mech system. Over the longer term frequent discretionary involvement will lessen the mechanical edge. Disc involvement generally lessens drawdowns but it also reduces overall profit in most cases.
If the disc involvement is mainly emotional then it's going to make things much worse than the mech system. DDs will be larger and profits will be smaller. The aim then is to make the disc involvement more rule based (mechanical).
An example of this would be discretionary selling after news of an accounting irregularity rather than waiting for the EOW signal. This news is likely to cause further selling and a quick exit may save money over the mechanical EOW signal. So long as the discretionary involvement is rule based it can be tested to ensure it adds to the edge of a mechanical system.
I'm another RealTest convert.
Great software which continues to get better with every update plus VERY helpful and friendly support.
I converting my AB AFL code to RT scripts and for a while kept them in sync to make sure they gave the same results but eventually gave up. My confidence in RT grew but I also started making changes which I found difficult to copy in AB.
The best purchase I've made in ages.

To be honest, using option to protect my portfolio has cost me heaps and I gave up: between the fees from my broker, the decay, the low liquidity it has been a one way to burn money for me.

Christmas
I asked what my wife would like for Christmas.
“A divorce”
I had to tell her that “I wasn’t planning on spending that much”

@qldfrog thank you for responding, I appreciate all responses. In my case for this system I'll be using option trades as the only type of trade to be used within the system, for protection I'll be using stop-loss option orders to exit a trade. These are the same as a standard stop-loss order, it's just an order to exit at a certain price.You are aware of the costs of purchasing options to protect yourself, and the need to cycle these as they approach expiry;

@ducati916 thank you for the time and effort you put into your responses. In my recent journey learning about options I have become aware of these things that you have mentioned. I've been taking option trades alone the way as I've been learning and early on I experienced the situation where the market went up and my Call option value went down, at time my mind's voice shouted 'what the fu*k', but I've come to understand options to a point now that I feel like I can really make them work for me.Without knowing more detail any advice could be somewhat inaccurate. However there are some very broad generic risks that you would need to manage.
(a) Volatility risk: as in IV crush. Think of it this way: the underlying does not change in price but for whatever reason, people are buying the option. The Option is a derivative (price) of the underlying but, the price of the Option still rises. This is the IV. When/if the underlying does move higher, the Option resets as against the underlying. This can however be LESS than the earlier price. This is the air coming out of the inflated Option price: the IV. What we have now is the HV as measured by the move in the underlying.
(b) theta risk: this depends on the duration (expiry date) of the Option purchased (sold) and the acceleration of theta decay into the last 30 days of life. Generally speaking, you do not want to hold a bought Option (unless it has moved DITM) to expiry. theta decay really accelerates into this time period, enough potentially to trigger a stop loss sale as indicated in your MM plan.
(c) gamma/delta risk changes quite dramatically as Options move in/out of the money. This can work for you if you are buying Options. So obviously, this should be a consideration when setting up your positions.

You are bullish on silver with a 17 March 2023 expiry: current price is $22 +/-
What is the better play: ITM, ATM or OTM? (I have no idea currently I just picked a random ticker). This feeds directly into your options for setting up a trade, particularly in your stop losses for closing a position.

and it's always worthwhile to describe the various risks involved in trading, new information for some and a useful reminder to others.theta decay really accelerates into this time period, enough potentially to trigger a stop loss sale as indicated in your MM plan.
@peter2 you have made all good points here, a helpful check list;@DaveTrade Good luck with this activity, hope it goes well and keep us posted please.
(i) 12.5% risk is a lot unless you're prepared for it. I'd use this risk level in a smaller account but would be too much for me in a large one. I hope your worse case isn't losing 12.5% in one week.
(ii) Correlation between your underlying markets needs to be considered carefully to manage total risk.
(iii) Total directional risk needs to be considered. Are you going all one type of option or a mixture?
(iv) I'd be careful placing exit stops in the options market. They have a habit of being hit when liquidity thins suddenly.
