Intsingiselo kunye nokusetyenziswa okubonakalayo kwesalathisi seDEMA

Ukuze udale inkqubo yokurhweba esebenzayo, kuyimfuneko ukumisela ngokusemandleni aphezulu umzuzu ongcono kakhulu wokungena kurhwebo. Kule njongo, ukuzaliseka kwangaxeshanye kweemeko ezimbini kusetyenziswa:

1. Umkhwa unqunywe, ngokuhambelana nexabiso eliguqukayo ngoku.
2. Kuvela imeko apho kunokwenzeka ukuba ungene kurhwebo kwicala lomzila kunye nokuyeka okuncinci kunye nenzuzo enhle enokubakho.

Enye yeendlela zemveli zokumisela umkhwa kukusebenzisa amaxabiso aphakathi kwinani elithile leebha (iziphatho zamakhandlela kwitshathi). Umzekelo, ukonyuka komndilili (i-SMA) yamaxabiso angama-24 okugqibela kwitshathi yeyure ibonisa indlela apho itshati itshintshile kwiiyure ezingama-24 ezidlulileyo. Ukungalungi okuphambili kwesalathisi esinjalo kukulibaziseka kwayo. Ke, umrhwebi, ngokusekwe kwimiqondiso yakhe, unokuphoswa lula ngumzuzu olungele ukungena kwintengiselwano. Izixhobo zokuhlalutya kobugcisa zihlala ziguquka kwaye, ngokukodwa, oku kuye kwakhokelela ekuveleni kwendlela ekhethekileyo yokubala imiyinge – EMA. Umahluko wayo ulele kwinto yokuba xa kubalwa umyinge, amaxabiso athathwa ngemilinganiselo ethile, kwaye le yokugqibela iya kuba ngaphezulu. Ngaloo ndlela, umyinge uya kubonisa ubukho bomkhwa, kodwa ukulibaziseka kwayo kuya kuba ngaphantsi xa kuthelekiswa nomyinge oqhelekileyo. Isalathisi se-DEMA luphuhliso olongezelelweyo lwalo mbono. Kule meko, okokuqala, i-EMA ithathwa kwixabiso le-asethi, kwaye emva koko kwi-EMA efunyenweyo, ithathwa kwakhona. Isalathisi esinesiphumo sinokulibaziseka okuncinci phakathi kwezalathi ezifanayo. Umzobo wendlela ezisebenza ngayo iintlobo ezahlukeneyo zomndilili
Ke ngoko, i-DEMA inokusetyenziselwa zombini ukumisela umkhwa kunye nokufumana owona mzuzu unengeniso yentengiselwano. Oku kubangelwe ikakhulu kukulibazisa okuncinci.

Ukusetyenziswa okusebenzayo

I-Double Exponential Moving Average ingasetyenziswa ngokuthe ngqo, kodwa iqhele ukusetyenziswa ngolu hlobo lulandelayo:

1. I-EMA ibalwa ukusuka kumaxabiso exabiso le-asethi.
2. Bala i-DEMA ukusuka kwesi salathisi.
3. Isalathisi = ( 2 x EMA ) – DEMA.

Lo mndilili unokusetyenziswa nangezinye iindlela. Ukusebenzisa i-DEMA kukuvumela ukuba ubone ubukho botshintsho lwexabiso. Ukuba le yokugqibela ingaphezulu kwesalathisi, ke imeko iphezulu; ukuba ingaphantsi, iphantsi. Le ndlela ikuvumela ukuba uvavanye ngokuchanekileyo umkhwa, kodwa umrhwebi kufuneka akhethe umyalelo womlinganiselo osetyenzisiweyo.
Lo mndilili ngexesha lokuhamba kwe-trend ungathathwa njengomgca wokuchasana oguquguqukayo (ukuba ishati yexabiso iphantsi) okanye inkxaso (ukuba iphantsi). Ijika elinjalo lingasetyenziselwa ukuvula urhwebo kwi-rebound. Ukudibana komgca oguqukayo kunokuqwalaselwa njengomqondiso wokuphuma kurhwebo oluvulwe ngomkhwa. I-DEMA ingasetyenziswa njengophawu lokungena kurhwebo. Ukuba, umzekelo, ixabiso liwela isalathisi ukusuka ezantsi ukuya phezulu, ngoko unokuvula isivumelwano sokuthenga i-asethi. Ungasebenzisa indibaniselwano ye-2 DEMA ngamaxesha ahlukeneyo. Ngokomzekelo, unokukhetha i-21 emfutshane, kunye ne-50 ixesha elide.Umrhwebi kufuneka anqume ixabiso elichanekileyo ngokusekelwe kwisicwangciso sorhwebo asisebenzisayo. Isalathisi esicothayo sinokusetyenziswa njengendlela yokumisela umkhwa, kunye nokudibana kokufutshane kunye nexesha elide njengomzuzu olungileyo wokuvula isivumelwano. Xa usebenzisa i-DEMA, kufuneka uthathe amanyathelo asekelwe kwisicwangciso sokurhweba. Oko kukuthi, lo mqondiso akufanele ucatshangelwe ngokuzimeleyo kwiminye imithetho yenkqubo yokurhweba. Umzekelo yile meko ilandelayo. Masithi ixabiso lihamba kwi-uptrend ngaphakathi kwepaseji. Ukuba iphula umgca wenkxaso we-sloping ephantsi kwaye isalathisi se-DEMA sisebenza kwicala elifanayo ngexesha elifanayo, ngoko sinokucinga ukuba amathuba orhwebo olufutshane oluyimpumelelo luya kwanda. Umzekelo worhwebo:

Uyisebenzisa njani iDEMA kunye nendlela yokuyimisa

Ukusebenzisa isalathisi se-DEMA, kufuneka ukhethe ixesha laso. Imisela inani leebha zokugqibela ekubalwa ngazo.
Ngokuqhelekileyo, xa usebenza ngamaxesha ahlukeneyo, umrhwebi ukhetha inani alithatha njengelona lisebenzayo. Ngokomzekelo, abanye abantu bacinga ukuba kwiitshathi zeyure kungcono ukuthatha ixesha le-24. Ukuba uceba ukusebenzisa esi sibonakaliso, kufuneka uthathele ingqalelo ukuba ayikho phakathi kwezinto eziqhelekileyo. Inkqubo yofakelo ixhomekeke kwitheminali oyisebenzisayo. Ngokomzekelo, isicelo esithandwayo seMetatrader 4 sibonelela ngenani elithile lezibonakaliso zesiko. Unokukhuphela i-DEMA, umzekelo, kwikhonkco http://fox-trader.ru/wp-content/uploads/2015/09/DEMA.zip. Ukuyisebenzisa, kufuneka uthathe la manyathelo alandelayo:

1. Okokuqala, i-archive enesiphumo kufuneka ikhutshwe.
2. Kufuneka uqalise iMetatrader 4, emva koko uvule iMetaEditor.
3. Kwimenyu ephambili, yiya ku “Fayile”, emva koko ucofe ku “Vula”.
4. Khetha ifayile yesalathisi ye-DEMA engapakishwanga kwaye uyivule.
5. Emva koko nqakraza kumgca othi “Gcina njenge”. Emva koko, ifayile iya kugcinwa kwisalathisi sezalathisi.
6. Emva koko kwi-Metatrader yiya kwimenyu ethi “Jonga” kwaye uvule umqhubi wenqanawa. Kwikhathalogu yesalathisi, cofa kabini kwi-DEMA.
7. Emva koko, ibonakala kwitshathi.

Ifayile ekhutshelweyo kwikhonkco enikelwe apha ikwaqulethe isalathisi se-DEMA MACD. Ifakwe njengoko kuchaziwe apha. Ukusetyenziswa kwesalathisi kuchazwe kumfanekiso oqhotyoshelweyo. Ukusebenzisa i-DEMA MACD:
Itshathi yongezelela inika uthelekiso kunye ne-MACD yakudala. Inokubonwa ukuba ukhetho olusebenzisa i-DEMA lunika imiqondiso echanekileyo ngakumbi. Iindidi zemiyinge ehambayo (SMA, WMA, EMA, DEMA, TEMA): https://youtu.be/2fzwZAScEDc

Umahluko kwizalathi ezihambelanayo

Xa usebenzisa i-DEMA, umbuzo uvela malunga nokuba kufanelekile ukunciphisa ukulibaziseka kwesalathisi ngokuthatha i-EMA ukusuka kwesi salathisi kwakhona (isalathisi esifunyenwe ngale ndlela sibizwa ngokuba yi-TEMA). Kwangaxeshanye, kufuneka kuqondwe ukuba utshintsho olucothayo kumyinge lunceda ukucacisa ngokuchanekileyo ulwalathiso lwenguquko yenguqu.
Ukuba unyusa ubuntununtunu bomndilili, ngoko iya kubonisa utshintsho lwangoku lwexabiso kumlinganiselo omkhulu xa kuthelekiswa nokuboniswa kwendlela. Ngexesha elifanayo, ukusetyenziswa kwesalathisi kuya kuba nenzuzo ngakumbi kwintengiso yexesha elifutshane. Xa kuthelekiswa ne-avareji elula okanye ecacileyo, isalathisi se-DEMA sine-lag encinci kwaye sinikeza iimpawu ezichanekileyo.
