NEW YORK (TheStreet) -- Point-of-sale electronic-payment device maker VeriFoneSystems (PAY) is scheduled to report quarterly results after Tuesday's closing bell. VeriFone has been a household momentum stock since its March 2009 low of $3.65 until its all-time high of $58.88 in April 2011.

The daily technical chart for VeriFone indicates that a positive reaction to earnings should pull the stock above its 200-day simple moving average. Yet the weekly technical chart shows the opposite scenario. Thus, investors should proceed cautiously before this stock.

Since then, it's been crucial for investors to track and capture the volatility between price highs and lows in VeriFone shares. Daily and weekly price charts can help investors do just that.

Analysts expect the company to report earnings of 32 cents a share for its quarter ended in January. During the quarter VeriFone partnered with First Data on solutions for preventing the potential theft of customer personal data exposed during checkout swipes at store registers.

Here's a look at VeriFone's performance measures and key trading levels based on an analysis of daily and weekly charts.

VeriFone Systems gained 39% last year but was down almost 8.3% so far this year as of Monday's closing price of $34.13 and is 12% below its Dec. 23 52-week high of $38.62. As of Monday's close, the stock was up 12% since trading as low as $30.39 on Feb. 2. At midday Tuesday, shares were changing hands at $33.22, down 91 cents, or 2.7%.

Investors looking to buy VeriFone after earnings should place a good-'til-canceled limit order to purchase the stock if it drops to $33.18, which is a key level on its technical charts for the remainder of March. Lower key technical levels at which to buy are $29.55 and $27.53.

Investors seeking to reduce their holdings of VeriFone should employ a sell stop below the stock's 200-week simple moving average of $33.03.
