![]() ![]() Optical Flow interpolation is ideal for modifying the speed of clips that contain objects with no motion blur, which are moving in front of a mostly static background that highly contrasts with the object in motion. ![]() Choose Render In to Out or hit Enter to do that To see the optical flow effect, render your sequence. For low quality or draft rendering, the faster Frame Sample interpolation is used even while the Optical Flow is enabled. Since the optical flow library cannot sustain real-time playback, as it happens with the existing Frame Blend function, Premiere Pro uses the time-consuming Optical Flow only for Time Remapping for high quality renders. The Optical Flow option in the Time Interpolation menu ( Clip > Video Options > Time Interpolation > Optical Flow) allows you to interpolate missing frames for time remapping and produce better looking and smoother slow motion from conventionally shot footage. The Optical Flow feature in Premiere Pro uses frame analyses and pixel motion estimation to create brand new video frames, resulting in smoother speed changes, time-remapping, and frame-rate conversion.

![]() ![]() ![]() I do think that AccuBattery uses a different system, where it counts even charges by 20% (example 40% to 60%), possibly making it less accurate. Something else I like is that Battery Gury calculates battery health based on specific conditions (when battery is charged from 15% to 100%) and it also gives you notifications when the charging limit is reached to more accurately calculate battery health: the notification will ring a while -after- reaching 100% so the calculation will be more accurate. Granted, Battery Gury is pretty basic in this aspect (it's showing partial and kernel wakelocks but not wakelock alarms), but it does it's job. That's two apps, whereas Battery Gudy provided the same functionality within the same app. More info here.ĪccuBattery doesn't have that feature, so when I used it I had to resort to BetterBatteryStats to view wakelocks. I used to like Accubattery a bit more mostly due to it's design, presentation and all, but now I would suggest Battery Gury for one main reason: it allows you to view wakelocks, so you can possibly identify apps which drain your battery (you can enable it with root or with ADB commands). Honestly it's probably worthwhile to try all 3 apps and see which you prefer (unless you have a phone with Android 13, in which case don't bother with GSam). The presentation of per-app battery usage is definitely better. Some aspects of the UI also seem simpler/cleaner in Accubattery. This may vary based on the device type and/or Android version. I installed Accubattery again today, and so far it looks like it is using less battery than Battery Guru. Battery Guru has ads or a subscription, neither of which I'm fond of. One thing I do prefer about Accubattery is that is has a one time payment option to unlock Pro features. However, it hasn't been updated for almost a year, and doesn't work properly on Android 13. I provides good stats, and uses very little battery to do so. GSam Battery Monitor is also a good alternative if you don't need battery health estimation and have Android 12 or older. Battery Guru is in active development and is updated frequently. It also hasn't been updated for over a year. Accubattery used more battery while running in the background. The battery health estimations were within a few percent of each other. I had both installed on my phone for a while, so I could compare them directly. ![]() ![]() In other words, the universal benefit of the HMA is that it provides a faster signal on a smoother visual line. That is why the main difference between the HMA and the other moving averages is that it responds to price changes quicker and can help confirm a trend or signal a price change at the right time. Namely, their inability to isolate market noise and avoid lag. However, it is designed to improve their main flaw. The Hull Moving Average is very similar to other moving averages in how we interpret them. On the other hand, once the market embraces a bearish trend and the indicator also starts to go down, that might be a good opportunity for going short. Its fundamentals are rooted in a basic concept – if the indicator rises, the prevailing trend is also going up. Instead, he recommends looking at turning points to identify entries and exits.īased on this, the strategies you can use with the Hull Moving Average are as simple as they get: The reason is that crossovers are likely to be distorted by lag. Hull Moving Average Trading StrategiesĪccording to Hull, the indicator’s signals are most efficient when using them for directional signals and not for crossovers (i.e., when a shorter-term MA crosses a longer-term MA). ![]() Usually, when using a shorter period HMA, the entry signals are primarily in the prevailing trend direction. On the other hand, shorter periods can be more beneficial to day traders who want to capture price movements as they unfold in real-time. If you choose a longer period, you can use the HMA to identify trends more effectively, making it a better choice for long-term trading. You might see the HMA use various different colors on some platforms when depicting bullish or bearish trends.īefore we switch to the trading strategies you can apply with the HMA, we should take a minute to focus on the best timeframes for the HMA and their effect on the indicator’s appearance and signals. Here is how the HMA looks on a 15-minute chart of the E-Mini S&P 500.Īs you can see, there is nothing significantly different from the way other moving average indicators appear on a chart. The combination of both is what allows the HMA to be so smooth and responsive. Meanwhile, we derive the latter from the direction of the current market slope. We use the former to determine the location relative to price. You have a positional value and a directional value. Most trading platforms display the HMA with two dimensions. Knowing this should make interpreting the indicator fairly easy. It determines whether the market conditions are bullish or bearish relative to historical data by relying on recent price action. HMA = WMA(2*WMA(n/2) − WMA(n)),sqrt(n)) How Can You Use the Hull Moving Average?Īs a directional trend indicator, the HMA captures the current market’s dynamics. Finally, calculate a Weighted Moving Average with a period the square root of “n” using the data from Step 2.Next, calculate a Weighted Moving Average for period “n” and subtract it from the one calculated during Step 1.First, calculate a Weighted Moving Average with period “n/2” and multiply it by 2.Calculate the Hull Moving Average by following the steps below: We’ll need to know how to use the Weighted Moving Average (WMA). ![]() ![]() However, it is still a robust tool for traders because it generates a smooth line that makes it easy to work with.Ĭalculating the indicator is straightforward. It is just a variation of other moving averages (SMA, for example). In reality, there is nothing especially unique about the HMA. Today, swing and long-term traders apply it to complement other indicators or confirm trading signals combining various in-depth analysis techniques. ![]() “It almost eliminates lag altogether and manages to improve smoothing at the same time.” Back in the day, he introduced the technical trading tool with the following claim: Some traders also use the indicator to time their entry and exit signals.Īlan Hull, a trader, mathematician, and IT expert developed the HMA in 2005. The result is a moving average that’s dynamic yet smooth, able to help identify the dominating market trend. It prioritizes recent price changes over older ones. The Hull Moving Average indicator is a combination of weighted moving averages (WMAs). Its goal is to provide more information of higher quality to those whose trading strategy depends on the slim margins within the price movements of an instrument. The Hull Moving Average (HMA) is a directional trend indicator. Final Thoughts What is the Hull Moving Average? ![]() ![]() ![]() You can create only one marquee for one thumbnail image.
