The 0-DTE strategy is a style of options trading that relies on the fact that options lose value over time. This might sound like an obvious statement to make – after all, it’s one of the most fundamental truths of trading options. However, by looking at historical data and calculating a theoretical P&L curve based on pure time decay, we can see just how powerful this strategy has been in the past when applied correctly.
Risk per Trade
Risk per trade is the maximum amount of money you can lose in a single trade. It is a function of position size and margin, as follows:
- Risk per trade = Position Size x Margin/100000.
To calculate your risk per trade, multiply your position size by your margin (as a percentage). Then divide by 100000 to convert it into micro-lots (1 micro-lot = $1).
Win rate is the percentage of trades that are winners. A strategy with a win rate of 45% means that for every 100 trades, you’re making 45 profits and 55 losses.
The higher the win rate, the better the strategy—but there’s no magic number here. You should be aiming for approximately 50%, but some strategies may need to be more aggressive or conservative, depending on their entry criteria and exit strategy. For example, suppose you’re trading an extremely volatile asset with wide price swings. You might want to have a lower win rate because it allows for greater profitability over time as long as your average profit per trade is still positive (i.e., if your net profit is 10% over many trades). On the other hand, if you’re trading an asset with less volatility and smaller price movements (like gold), having a higher win rate would allow for less risk.
There are several strategies you’ll want to keep in mind when it comes to trade management. You should always stop losses and take profits when your trade goes against you. Another option is setting trailing stops (for example, setting a trailing stop at 10% away from your entry price). This allows flexibility if the market moves against you and captures more of the move in any direction. Another popular strategy is using profit targets. If your chart appears to be going through an overbought or oversold condition, then adding on profit targets can help manage risk while allowing for potential gains on the trade.
Another useful tool that’s often paired with these other strategies is Parabolic SAR (price action indicator), which uses moving averages and price patterns to identify possible reversals in trend direction and areas where reversal may be imminent.
Use SPY, Not SPX
The first thing to know about the 0-DTE strategy is that it uses SPY, not SPX.
What’s the difference? There are two major stock market indexes: the S&P 500 Index (SPX) and the S&P 500 ETF (SPY). SPX represents a basket of stocks with equal weighting, while SPY is an exchange-traded fund (ETF) that holds all 500 stocks in its portfolio. So when you see “S&P” or “SP,” make sure it’s referring to one of those two indexes rather than another index entirely — otherwise, you might be using an old version of this strategy.
Use a Broker with Tiered Margin
The margin requirements for different SPY contracts can be found here. The minimum initial margin needed to open a position is 10% of the contract’s value. For example, if you buy $1,000 worth of SPY with a current price of $280 and a margin requirement of 10% that means your initial margin would be $280 * 10%. This can be calculated as follows:
- Contract Value ($1,000) / Initial Margin Requirement (10%) = Number of Contracts
- ($1,000) / (.1) = 10
The 0-DTE Strategy is one of the most powerful ways to trade SPY.
The spx 0dte strategy is one of the most powerful ways to trade. It combines a trend-following system with a mean-reversion system, perfect for day traders who want to profit from trending moves and reversals.
The strategy was designed by Doug Benter in 1993 and was originally intended for use with the S&P 500 futures contract (SPX). However, we’ve found that this strategy works even better when applied to single stocks or ETFs such as SPY.
The 0-DTE strategy is one of the most powerful ways to trade SPY. Be sure you’re using a broker that allows tiered margin, and learn how to manage risk and win rate to make consistent profits.
