EBRO: SEDIMENTOS, EMBALSES Y DELTA

Esta imagen de @Sentinel2-@CopernicusEU del #DeltadelEbro muestra una espectacular #pluma de #sedimentos. La mayor parte de ellos no alimentará las playas cercanas. A veces lo olvidamos (va #hilo👇).

1- Acotemos el contexto. Aquí consideraremos sedimento al material no consolidado transportado por el agua y constituido por diversos fragmentos que provienen de la erosión de rocas preexistentes. Esos sedimentos, llamados clásticos, se clasifican según su tamaño de grano (ø).
2- Puntualicemos que, si llegan a consolidarse, las gravas (ø > 2 mm) formarán conglomerados y las arenas (63 μm < ø < 2 mm) areniscas. Los materiales finos, limos y arcillas (ø < 63 μm), se convertirán en lutitas.

#Straddles vs #Strangles ( Sell only )

These are the most common #Options strategies when one would start with #OptionsTrading.

Let’s understand from a broader perspective what’s the difference between these two.
Would not like to discuss the construction difference between them if you don’t know stop trading #options

#Straddles

You get higher premium so pnl would be higher compared to #strangles

But from where are you getting higher premiums is that your selling 0.5 #delta.
So probability of one going wrong is always 50% so to simply put one side is goin to get stuck in a #straddle but then market tends to #flucuate a lot so there is always the case of #meanreversion if you have selected the #strike rightly.

#ITM Vs #OTM #Options Which to #BUY?

When selecting the right #option to #buy, a #trader has several choices to make. One is whether to purchase an in-the-money (ITM) or out-of-the-money (OTM) option.
While the goal for "#vanilla" #buyers is to have the option be in the money at expiration, the selected option depends on the amount the trader wants to spend and their risk tolerance, as well as their specific expectations for the underlying stock.
UNDERSTANDING #ITM Vs #OTM

Before delving into the pros and cons of each, let's look at what it means to be itm or otm.
A #call is ITM when the underlying stock is trading above the strike price.
Conversely it is OTM when the underlying stock is trading below the strike price
