IndexError: List index out of range

Bonjour à tous !

Pour vous expliquez brièvement, j'ai trouvez un bot sur twitter qui référence le RSI (indicateur utilisé dans le trading) c'est une valeur de type float.

Toute les 5 minutes le Bot poste les RSI les plus bas des crypto monnaies. Mon but étant de réussir a "grab" les RSI des crypto monnaies pour pouvoir ensuite les analyser. Je récupère aussi le Volume des crypto monnaies grâce à un module développé grâce a une API sur le site bittrex.com. Pour cette étape tout marche très bien je n'ai aucun problème.

J'utilise tweepy pour le stream listener twitter.

Voici un exemple de format de tweet qui est poster:

Citation:

5 min #RSI Signals:

$BTC - $SLR: 35.85
$BTC - $VRM: 36.5
$BTC - $BCC: 36.52
$BTC - $ENG: 37.81
$BTC - $WAVES: 39.8

$ZCL $CLOAK $PKB $SC

J'arrive à récupérer le coin en question et le RSI aucun soucis.

Le problème est que je lance ça sur mon serveur OVH (sous Linux) et que je le laisse tourner 24/24 en permanence grâce à screen.

En faisant ça je me suis rendu compte que parfois j'obtenais cette erreur de manière récurrente que je n'ai pas réussis à résoudre.

Je ne sais pas pourquoi mais parfois sans raison j'obtient un List index out of range.

Je ne sais pas de quelle ligne provient l'erreur puisque il m'indique l'erreur a la fin du fichier.
