Smart Sizing

2022年4月8日

Smart Sizing is a simple indicator designed for stock traders to quickly see how many shares you should ideally trade to have an equal amount of risk on all of your trades. It uses your inputted values along with the ATR to determine the right amount of shares you should trade. Since every stock has a different level of volatility just simply buying 100 shares for every trade for example or an equal $ amount like $10,000 will leave your portfolio with concentrated risk in some stocks. If the more volatile stocks turn out to be losers then the wins from the less volatile stocks may not cover the losses, however if your positions were sized according to the volatility of each stock it may have resulted in being profitable overall instead.

That's what the Smart Sizing indicator does, it tells you directly on the chart in a small table and right next to the indicator a value that is how many shares to trade according to your account value and risk objectives. You simply enter in your account value in the indicator settings (I update mine everyday), what % of your account you want to risk, and what ATR Length and Timeframe you wish to use. For example, if you entered your account value at $10,000 with risk percentage at 1% and if you used the daily ATR which was 0.50 then it would show as 200 shares (10,000 x 0.01) / 0.50 = 200 and by trading 200 shares that means if the stock went against you by 1 daily ATR it would equal 1% of your account. So if you used a ATR trailing stop or a fixed stop based on the ATR this indicator can help you determine what your correct position size should be so you can practice good risk management.

Take the example below of two stocks with an almost identical price, Citigroup C with a last traded price of $50.03 and Exelon EXC with a last traded price of $50.02, you can see the Smart Sizing indicator is showing to trade 59 shares on Citigroup and 130 shares on Exelon, even though both stocks have almost the same stock price the different recommended position size is because Citigroup is much more volatile than Exelon which is a electric utility.





Please note this indicator is designed for stocks but could also be used for forex but shouldn't be used for futures. It can be used on any timeframe with stocks worldwide.
