Would anyone actually use a SPY 0DTE-specific backtesting platform?
Developer seeks feedback on a proposed SPY 0DTE options backtesting platform to validate market demand before further investment.
I’ve been working on a project for SPY 0DTE traders and wanted some honest feedback before I invest more time and money into it.
The idea is a backtesting platform focused specifically on SPY 0DTE options. Instead of general stock backtesting, it would let traders test entry conditions like RSI, MACD, VWAP, volume, time of day, and other indicators to see what has historically worked.
I’m curious:
Would you actually use something like this?
What features would be must-haves?
What’s missing from existing tools such as Option Omega?
I’m not selling anything right now—just trying to determine whether this solves a real problem before I continue building it.
Nope
No
Oh hell no! Your contract can go from up 300% to down 500% in like, 15 seconds. You can’t backtest for that crap. Too volatile. Would never use any automated anything for 0dte
Yes , I totally agree with this , how would u be able to back test the high volatility in seconds ? Maybe if u were able to put in a buy and watch it slowly how it goes up and down , but the truth is , is that what ppl want to back test ? I basically would be okay just looking at ordinary charts with minute candles or sometimes 5 minutes , how could past data effect your future decisions when your dealing with an entire market with news and earnings and what ever other million things that are going on and effecting the price change and not just like some big daily number but actually down and gritty to the last 1/4 of a penny on the nanasecond changing that even during real time trading I can barely keep track of the numbers , I just basically put in my order when I see I got direction and momentum and with a little investment and like a few minutes can pull out a couple k’s a day without the rest of hasssles and fussing
What percent do u pick for your stop losses?
OptionAlpha already has a 0dte and 1dte back testing for SPX, SPY and QQQ
ToS has OnDemand feature that allows you to choose a particular day/time in the past and sim-trade from that point forward.
Yes. The gap in the market is not another options analytics tool, its a proper replay engine where you can walk through 0DTE bars tick by tick and test exit logic against real intraday data. Most platforms just aggregate end of day PnL which tells you nothing about slippage or fill timing on 0DTE expiry day.
this is the way. simple and it actually works.
Are you directional with your 0 DTE ? Or do you like to sell premium ?
yeah, i think data is the most costly thing to build/back fill.
No
the only answer and data set traders probably only want are the days it didnt work and why they belw up.
there is already OptionOmega like you said, so youd be competing for the same customer if it works.
Maybe your 0DTE can show every SPY/SPX option chain on that day and minute to minute bid/asks historical, but that woudld cost you a lot.
If seeing the historical intraday snapshots is useful to you, you can check out the options calculator I built. The data resolution is 5-minutes and there's 3 years of history.

The historical snapshots part is quite new and has lots of room for improvement. But just seeing the past option chains and going through them should work fine. If you have opinions and suggestions, I would love to hear them!
Where are you getting per tick pricing?
