Backtesting ES with S&P500 Data...?

Recommended Posts

Can you backtest ES with S&P500 Data?

 

I don't plan to account for things like slippage and transaction costs rather I want to measure sure behaviours of the price action over the past few years.

 

Is it adequate to backtest the ES contract with the S&P500 data or am I asking for trouble...?

that depends on a lot of things

 

what is the resolution you are trying to trade?

minute charts? hourly charts? daily charts?

 

what is your risk tolerance?

obviously if you are scalping, the daily chart won't help. You have to find the medium between risk, and resolutions available to you.

 

do you trade globex? or hold positions overnight?

 

if you are a momentum trader at the daily level... i would think it should be ok.

Hey Tams,

 

I would define myself as a momentum trader at the daily level and no I don't hold positions over night.

 

The work I did last night on the ES regarding the past 10 days of data (Close prices on the S&P and Selected hourly bars from thinkorswim) confirmed my hypothesis that a derived from the data last night.

 

Do you have any suggestions in regards to momentum trading the ES and backtesting it by hand?

if you are dealing with daily data,

you can use excel.

 

otherwise a charting software is easier.

 

Ninjatrader is free.

 

MultiCharts is easy to program.

 

take your pick.

You might want to try doing some research on your trading platform or data provider regarding a "continuous ES contract" and see if they provide you with one for backtesting purposes. If not, then do a search and you'll find plenty of help on it. Good luck.

If you're just experimenting with ideas with daily data then it will be fine to begin with, but you'd surely want to test using real ES data before going live with a strategy.

 

One option to look at is http://www.prorealtime.com - sign up and they offer end of day futures data and a really great streaming platform (no need to install anything) completely free of charge. The language for backtesting in the platform is simple and they provide plenty of resources including a manual and example code.

 

Another good proxy for the ES is always the "Spider" Exchange Traded Fund.

 

Good luck!

    • Question: To those that had/have cancer, what were the signs that made you think “something is not right here” to make you go see a doctor? Answer: So, 5/25/2018, I woke up, got ready for work, and as I walked to my car, I started gagging. Like something was stuck in my throat and I needed to clear it. And then it went away.   But 10 minutes after that, I was T-boned at 40mph on the driver side door. But what made me see a doctor was while my muscles felt better and bruises were going away, the gagging still continued, I started having fevers, my neck felt swollen, I was having such a hard time breathing, and I'd have random sharp pains in my chest, but not from where the seat belt saved me.   2 weeks after the accident, I finally see an urgent care doctor, who looks me over, tells me I'm fine, but luckily requests a neck X-ray. And I ask for a chest X-ray, which he rolls his eyes but let me have (most of my pain was in the neck, so I understand).   The very next day, he calls and says “So, that chest X-ray shows there's a 4 inch mass on your heart and lungs, and your lungs have been filling up with fluid, as well as in your pericardial (heart) wall. We need you to come in tomorrow.”   Turns out the big mass, due to the accident, caused my heart and lungs to tear and fill with fluid, the swollen neck and gagging was caused by 2 metastasized tumors, and the fevers and weight loss were symptoms. Stage 4b Hodgkin's Lymphoma.   But thankfully, we went very aggressive with chemo (and had a lot of bad side effects that don't normally happen to patients), and now I'm about 16 months cancer-free. Yay lucky X-rays!

    • As a man, the reality of life is the harshest part. I don’t mind looking older or becoming weaker over time; it’s nature.   Have you ever heard that the only people who will be loved unconditionally are women and children? Men will only be loved as long as they can provide until they are no longer needed. It doesn’t matter if you already did your best to get your kids to the best school or get the best things for them, if you stop before they’re done with it, there will be no thank you. The only thing they will remember is that they have to quit school at 15, ignoring all the previous 15 years of life you provided for them. The only people who will accept you, no matter what, are your parents. But in this situation, you might be that ungrateful child.   EDIT: Wow, I didn’t think this would get so much attention.   For those who disagree, I can only say that everyone has their problem. If you don’t get the chance to face such a thing, be grateful. Remember, sometimes what you throw in the garbage is something that someone wishes ever to have.” – ElZee, Quora   Profits from free accurate cryptos signals: https://www.predictmag.com/
