Zuva Rekushandisa Kutengesa uye Applications yekufamba Mazana
Kufambisa nharaunda chiratidzo chekugadzira chinoratidza kuti mutengo wacho waenda sei, pachiyero, pane imwe nguva yenguva. Kufambisa miganhu kunoshandiswa kubatsira kusimbisa mafambiro, maitiro ekutsvaga maitiro uye kupa zviratidzo zvekutengeserana. Kune marudzi akawanda akasiyana-siyana ekufamba-shanduka, asi ivo vose vanogadzira imwe nzira yakarongedza iyo inogona kubatsira kuratidza kuti chii chinonzi mutengo uri kufamba.
Zviri nyore Kufamba Avhareji Kuverenga
Iko shanduko inoshandura inoshandiswa (SMA) inowanikwa yezvokupedzisira n nhamba, apo n nhamba yezvenguva iwe unoda muvhareji we.
- (P1 + P2 + P3 + P4 + ... + Pn) / n
Kwemakore mana SMA nemitengo ye 1.2640, 1.2641, 1.2642, uye 1.2641 inopa chiyero chinofamba che 1.2641 uchishandisa kuverenga [(1.2640 + 1.2641 + 1.2642 + 1.2641) / 4 = 1.2641].
Kunyange zvazvo uchiziva kuverenga chiyero chakareruka unyanzvi hwakanaka hwekuita, kutengesa uye mapuratifomu mapurisa kuverenga zvose izvi kwatiri. Ingosarudza sarudzo yeSMA kubva pane zvinyorwa zvechati, shandisa iyo chati, uye uchinje nhamba yenguva inoshandiswa. Kugadziriswa kune zvikwangwani kunowanikwa mu "Zvirongwa". Pazvikwata zvakawanda, zvigadziri zvinowanikwa nekanyanya-kuvhara pane chinoratidza.
Kubatsira kweSMA ndeyekuti iwe unonyatsoziva zvauri kuwana. I-SMA inotarisirwa iyo inowanikwa mutengo wehuwandu hwemaawa muSMA kuverengwa.
Nhengo dzeSMA dzakakosha ndeye 8, 20, 50, 100 uye 200. Somuenzaniso, kana uchishandisa SMA zana-100, kukosha kwezvino kweSMA pane chati ndiyo inowanikwa mutengo pamusoro pemakore zana ekupedzisira (mutengo mabhaji).
Iyi chati inoratidza 50-sma SMA, pamwe chete nemuenzaniso wekutsvaga wekutsvaga (EMA) uye chiyero chekufamba chinorema (WMA) pane imwe miniti tsadhi chati. Pamusana pekuverenga kwavo kwakasiyana, zviratidzo zvinowanikwa pamatauriro akasiyana emutengo pane chati. Aya mamwe maitiro ehurumende anokurukurwa anotevera.
Exponential Moving Average Calculation
Iyo EMA inorema muvhareji wekupedzisira n nhamba, apo kuyerwa kunoderedza zvishoma nezvishoma nemumwe mutengo wekare / nguva.
Mune mamwe mazwi, mitengo yemazuva ano inopiwa kuwedzera kukura kudarika mutengo wapfuura.
- [Pedyo-yapfuura EMA] x (2 / n + 1) + EMA yapfuura
Mune makore mana EMA nemitengo ye 1.5554, 1.5555, 1.5558, uye 1.5560, uye kukosha kwekupedzisira kuva yakanyanya kupfuura, inopa ikozvino EMA nhamba ye 1.5558 uchishandisa kuverenga [(1.5560 - 1.5558) x (2/5) + 1.5558 = 1.55588].
Sezvakaitwa neSMA, mapuratifati ekuenzanisa anoita zvose EMA kuverenga kwatiri. Sarudza EMA kubva pane zvinoratidzirwa pakurongwa pane imwe nzvimbo yechando uye uiise pane chati. Enda muzvirongwa uye uchinje kuti inguva ipi iyo chiratidzo chinofanira kuverenga, somuenzaniso, 15, 50 kana 100-nguva.
IEMA inogadzirisa nokukurumidza kusvika kumutengo kushandiswa kupfuura SMA. Semuenzaniso, kana mutengo unodzokorora hutungamiri, EMA ichadzosa mazano nokukurumidza kupfuura SMA. Izvi ndezvokuti EMA inoshandisa kuwedzera kwekukosha kumatengo emangwana, uye kuderera kuduku kwezvinhu zvakaitika munguva yakapfuura.
Weighted Moving Average Calculation
IWMA ivhareji inorema yezvokupedzisira n nhamba, uko kuyerwa kunoderera nemutengo wekare. Ichi chirevo chakafanana kune EMA, asi kuverenga kweWMA kwakasiyana.
- (Mutengo X kuwedzera chiremera) + (Mutengo wapfuura nguva X kuwedzera kwechimwe chinhu-1) ...
MaWMA anogona kuva nezviremba zvakasiyana zvakagoverwa zvichienderana nhamba dzenguva dzinoshandiswa muhuwandu.
Kana pane zvitsva zvina unoda kuwedzerwa kuyerwa kwemuviri wekuti, saka kuwedzera kunorema kunogona kuva 4/10, nguva isati yasvika inogona kuve yakakura ye 3/10, nguva inotangira iyo inogona kuva nekuyera kwe 2/10, zvichingoenda zvakadaro. 10 ndiyo nhamba yakasarudzwa, uye uremu hwe4/10 hunoreva kuti mutengo wakangoshandiswa uchatora 40% yehuwandu hweWMA. Mutengo wemakore matatu akapfuura zvikamu zve 10% zveWMA kukosha.
Tora mitengo ye 90, 89, 88, 89, ine mutengo wakangotanga kutanga:
(88 x (4/10)) + (88 x (2/10)) + (89 x (1/10)) = 36 + 26.7 + 17.6 + 8.9 = 89.2
Chiyero chekufamba chinorema chinonyanya kugadziriswa kupfuura SMA ne EMA. Ikozvino puropu yemitengo inowanzopiwa huwandu hukuru, asi inogonawo kushanda neimwe nzira, iyo mitengo yezvakaitika inopiwa kuwedzera.
Kufamba Avhareji Kushandisa Zvokushandisa
Kufambisa miganhu kunogona kushandiswa pakuongorora uye kutengesa zviratidzo .
Kuti uongororwe, zvose zvinofamba-siyana mazano kubatsira kusimbisa chiitiko. Kana mutengo uri pamusoro pawo MA inoratidza kuti mutengo unotengeserana kupfuura wawakaita, pavhareji, pamusoro penguva iri kuongororwa. Izvo zvinobatsira kusimbisa an uptrend . Kana mutengo uri pasi pemakisi ayo MA inoratidza kuti mutengo unotengeserana kudarika pane, uye pavhareji, pamusoro penguva iri kuongororwa. Izvo zvinobatsira kusimbisa downtrend .
Apo mutengo unoyambuka kumusoro kwawo MA unoratidza kuti mutengo uri kuwedzera kuwirirana kune kwaive pane kare, nokuti mutengo wazvino kupfuura iye zvino wava mukuru kudarika wepakati. Kana iyo mutengo ichipfuura pasi ma MA inoratidza kuti mutengo uri kushaya kusimba maererano newaimbova kare.
Imwe nguva refu uye imwe nguva shoma-MA-semuenzaniso, 20 ne50-nguva-inogona kuwedzerwa pane chati panguva imwe chete. Apo mitambo 20 pamusoro pe 50 inoratidza kuti pfupi pfupi mutengo wekumhanya uri kutamira kumucheto. Apo nguva 20 MA inodarika pasi pe50 inoratidza kuti pfupi pfupi yekutengesa mutengo iri kuenda kune yakaderera.
MA inogonawo kuiswa pamwe nezvimwe zviratidzo kuti zvipe zviratidzo zvokutengeserana. An EMA inogona kupa zviratidzo zvekutenga kana ichibatanidzwa neKeltner Channels . Iro zano rinogona kusanganisira kutenga pedyo neEEM apo maitiro acho aripo uye mutengo uri kutora kubva kumusoro kweKhantner Channel.
Rumwe rudzi rwe MA haruri nani kupfuura mamwe; ivo vanongorara mavhareji mutengo zvakasiyana. Zvichienderana nezvesarudzo iri kushandiswa, rumwe rudzi rwe MA runogona kushanda zviri nani kune rumwe. Edzai zvakasiyana MA masangano uye ona izvo zvinokupa iwe nemigumisiro yakanakisisa. Iwe unogona kuwana kuti pamusika umwe neumwe unoda kugadzirisa zvirongwa zvako zvishoma. Sma 50-SMA inogona kupa zviratidzo zvikuru pane imwechete, asi haishande zvakanaka pane imwe. Kana imwe yemakore 20 EMA inogona kubatsira kusiyanisa mararamiro kune rimwe ramangwana rechibvumirano , asi kwete chimwe. Zvose ma MAs zvingori zvishandiso, kuzvidudzira zvinosvika kumutengesi, nokuti hapana chiratidzo chinoshanda zvakanaka nguva dzose kana mumamiriro ose emisika.
