This EFS writes the OHLC, Net and Net% values for the current bar at the bottom of the chart.
With intraday intervals the Net and Net% correspond to the Daily values. With all other
intervals they compare the current Close against the prior period of the same interval.
If the current close is higher than the previous, the text will show in blue, if lower in red
if unchanged in dark grey.
The number of decimals shown can be modified through Edit Studies. The default is 2 and can
be changed in Line 30.
The horizontal position of the text can be modified through Edit Studies (increasing the
number moves it to the right and decreasing it to the left). The default is 25 and can be
changed in Line 35.
This script works with all time frames. If used with intraday intervals one must have
getPrevOHLC.efs in the OHLC subfolder of the Formulas folder.
This EFS requires build 571 or higher and is enabled for auto-update (checkVersion)

A ME INTERESSA SOLAMENTE CHE MI RIPORTI IL VALORE DELLA MEDIA ESPONENZIALE A 20 PERIODI NELL'ULTIMA CANDELA(FRAME 5 MINUTI) (funzione caricata per la ema : c:\esignal\formulas\advanced\mesa software\eMESA1.efs)


CHI E' PRATICO.. A MUOVERSI IN QUESTO LINGUAGGIO DI PROGRAMMAZIONE CHE PER ME E' ARABO ...grazie

Gli studi MESA sono integrati nell'applicativo e non sono accessibili tramite efs e la formula eMESA1.efs cui fai riferimento non computa una media esponenziale.

SCUSA HO SBAGLIATO A PRENDERE IL PERCORSO DELLA EMA CHE USO..
IL PERCORSO CORRETTO E' :
c:\esignal\formulas\LIBRARY\EMA.EFS

[ACM]

New_trader
Copia e inserisci (in un'unica riga) il seguente comando al rigo 60 della formula ema.efs

drawTextPixel(120, 0, formatPriceNumber(dThisMA), Color.blue, null, Text.RELATIVETOLEFT|Text.BOLD|Text.RELATIVETOBOTTO M, "MS Sans Serif", 10, 1);

Questo comando scrivera in basso a sinistra nel grafico il valore della ema all'ultima barra.
Per spostare a destra o sinistra la scritta modifica il valore 120 (incrementandolo la scritta si sposta a destra diminuendolo a sinistra)
