QChartist build 271 is out!
What Else? What’s New about QChartist?
Good News : I still have some New Ideas in Mind to improve QC !
– I intend to implement Twelvedata data source to QC.
It will support intraday historical data (and even the 240 min TF!).
It will support Stocks, FX, Crypto, ETF and even Indices !
I believe that the implementation of Twelvedata will be a wonderful improvement because there was a lack of 240 minutes time interval.
I had to use the period converter to convert 60M to 240M, this was tedious.
With this new data source, 240M time interval will be finally built-in !
And cherry on the cake : the Live Chart Refresh mode will work on 240M TF, which will be perfect to follow the exit strategy with TMA_CG (System #3 Price Action System).
See https://twelvedata.com/docs for more info. Twelvedata rocks !
All that remains now is to get to work to program that. I just need to find some time. This will be done for the next build : 271.
– Another thing for the build 271 will be to add in the documentations that :
For Alpha Vantage Crypto Data Source, you don’t have to put the Cross Pair for the symbol :
the correct syntax for the symbol is : “BTC” or “ETH” (not “BTCUSD” nor “BTC/USD” which do not work)
– Another thing for the build 271 will be to add in the documentations that :
The Market Watchlist does not work under Windows 10 with WineHQ. But it works great under Windows 7.
If you want to use the Watchlist, all what you have to do is to run “winecfg” in the terminal and select “Windows 7” instead of “Windows 10”.
Have a nice weekend !

Canon Canon de Pachelbel en 432 hz – 8 acides aminés
Cette musique relaxante a la particularité d’avoir huit notes correspondants exactement aux huit acides aminés primordiales chez l’homme. On sait aujourd’hui que chaque acide aminé possède sa propre fréquence qui se fixe en oscillation. Ces huit notes essentielles font parties de notre chaîne polypeptidiques (chaîne de 10 à 100 acides aminés reliés). Son écoute pénètre notre corps qui va être stimulé dans la protéine d’activation de la GTPase. Cette activation permet aux circuits enzymatiques de réguler le métabolisme de la biosynthèse, tous les réactions chimique de notre corps, gestion du chaud et du froid, digestion, rythmes cardiaque etc. Dans sa composition Canon Pachabel a voulu s’assurer qu’elle fasse du bien quelque soit le moment où on la prend dans l’écoute, en lui attribuant de nombreux couplets sur des rythmes différents. Les basses ayant une fréquence de résonnance choisit par Pachelbel , elles viennent réconforter le thème initial au niveau du rapport entre les fréquences. La protéine nourrit par cette musique produit un puissant anti stress pour l’homme. Un seul conseil… écoutez là le plus souvent et vous verrez…

To conclude: QChartist and MetaTrader 4 are good free charting software alternatives and they are complementary. They are a good and powerful combo when used together because there are some things that QChartist can’t do and some things that MT4 can’t do. Together, they can do many things, otherwise everything !
Are you rather Windows or Linux ?
Why do i prefer Windows ?
- Compatible with most softwares apps and games available on the market
Why do i prefer Linux ?
- Prevents eavesdropping from Google, Microsoft, Akamai and Amazon when Online on the Internet
- Prevents waste of CPU resources from these companies
- As a result, CPU Fan is less used and thus the computer is now completely silent
- WineHQ seems to be faster and more stable
To conclude : I have no preference between Windows and Linux since they are complementary.
It depends on the usage that you do with your computer.
