Despite its size, FX is among the least transparent markets globally. Unlike equity markets, FX is a decentralized or over-the-counter OTC market, where different currency rates can be valid at the same time, as long as buyer and seller agree on a price. The fact that there is no central authority, also unlike equity markets, contributes to the opaque nature of the FX marketplace.

Its size and volatility make it too important and unpredictable for organizations to overlook. Global market movements and fluctuations in currency exchange rates affect job functions across the organization on a daily basis — and in some cases, in real time. There are many different types of FX data sets to choose from, so how can professionals understand which is best for them?

This guide identifies the ideal FX dataset based on job function and business need. As masters of navigating the tumultuous business landscape, accountants, and more broadly finance professionals, use daily average exchange rates to serve their day-to-day functions. These daily average rates are the calculated average of the currency intraday fluctuations and can be conveniently populated inside ERP systems and other financial applications. In certain circumstances, other period averages may also be required, including weekly, monthly, quarterly, and yearly averages, though all are available when subscribing to a daily average feed.

In some cases, Central Bank exchange rates will also be required in place of market rates, to comply with local regulations when companies are operating within certain territories. To complicate things, auditors often work outside their office visiting clients onsite across the globe. Because of this, auditors need a flexible cloud-based tool to provide access to historical exchange rates anytime and anywhere.

The data should be also be downloadable and customizable in order to compare multiple currencies at one time as well as choose the type of rate needed, such as bid, ask, or midpoint, or use a specific Central Bank as the source of data on a case-by-case basis. And with single seat and multi-seat contracts available, this tool is the choice of CPAs and large audit firms, alike.

Conversely, in a stationary setting, an API subscription is recommended, as auditors need accurate and reliable daily average exchange rates that automatically pre-populate within financial and reporting tools. Hedge fund managers and fintech professionals use tick-by-tick foreign exchange data or a trading platform order book to power sophisticated and big data analysis and research for high-frequency trading, algo-trading, market modeling, interactive charting, financial tickers, backtesting, managing FX risk, and more.

Tick-by-tick data is updated every time an exchange rate changes — which can be many times a second — and delivers large batches of data on the millions of exchange rate movements throughout a single day.

This type of data is used for calculations that require a true, real-time view of the FX landscape. The key here is to retrieve data from an actual market participant, such as OANDA, that can provide an absolutely accurate view of the market at any point in time. In other instances, the OANDA trading platform order book can be used to view open FX orders both buy and sell as well as open positions for a period of time the previous 24 hours is usually common practice.

Open orders could be interpreted as an indicator of the price expectations that are contributing to natural resistance and support levels, while open positions could be an indicator of market reaction to price changes and the pressure on prices due to unrealized profit and loss. Order book data provides excellent stats and insights into foreign exchange market sentiment.

In the current economic environment, managing corporate financial risk and cross-border cash flows is not an easy task. Multi-currency risk management was once a relatively straightforward part of the treasury job; however, persistent FX market volatility has changed all that. This means that treasurers who are masters of multi-currency cash management need a specific set of data to facilitate successful risk management as well as FX exposure summaries, FX gains and losses, hedging positions, and hedge coverage ratios.

With so many data sets in the mix, automation becomes an absolute necessity. Standard business procedures for finance and treasury professionals has evolved into an almost entirely automated environment.

API delivery of data guarantees an uninterrupted flow of up-to-date information while offering flexibility to plug the data stream directly into ERP and treasury systems — all while maintaining accuracy of data and reliability of delivery.

This is especially true for spot rates, which enable treasurers to select the exact time of day or fixing they need rates for as well as forward rates, which allow treasurers to lock in an exchange rate for the purchase or sale of a currency at a future date.

Dans cet article je vais vous apprendre comment utiliser les bandes de Bollinger , aussi connues sous le nom de courbes de Bollinger , ou, plus simplement, les Bollingers. Il est incontournable quand on veut apprendre le trading. Les deux dernières sont calculées en appliquant plus ou moins 2 écarts-types par rapport à la moyenne.

Au centre se trouve la moyenne mobile à 20 jours. Au-dessus la bande de Bollinger supérieure. Au-dessous la bande de Bollinger inférieure. Une bulle est caractérisée par une divergence des bandes inférieures et supérieures: Les cours sortent du canal précédemment formé par les deux bandes auparavant.

On dit que la volatilité augmente. On voit le rétrécissement à gauche. Ceci est vrai pour toute bulle de Bollinger haussière. Que se passe-t-il après une bulle?

Sans indicateur supplémentaire comme par exemple le MACD on ne peut pas vraiment dire. Mais il y a 3 cas possibles:. Si la tendance continue on assistera à une autre bulle ou à des parallèles voir ci-dessous. On aura alors une autre bulle comme sur le graphique ci-dessus. On aperçoit bien le retournement de la bande de Bollinger opposée de la première bulle sur les parallèles baissières à droite on observe juste une déviation. La première bulle se transforme en parallèles. Un premier pic est réalisé, mais les cours montent encore plus haut, formant une seconde bulle.

Les parallèles se terminent par un retournement de la bande de Bollinger qui se trouve du côté des cours. Ce retournement indique un essoufflement du mouvement.

Les secondes parallèles sont plus longues. On voit bien le canal. Sur la fin de ces parallèles on constate deux pointes vers le bas. En réalité les vraies parallèles sont plus longues que cela. On dirait plus deux bulles consécutives. Ci-dessous il y a des incursions sous la MM Ci-dessous à gauche une bulle après un rétrécissement successif à une bulle qui pourrait être assimilée à des parallèles les retournements de la bande de Bollinger opposée sont invisibles tellement les retracements après les creux sont faibles , puis des parallèles vraiment longues.

Vous aurez remarqué que les cours restent au-dessus de la MM20 la plupart du temps dans les bulles. Quand la force du mouvement est faible, il y a des incursions de courte durée sous la MM Parfois les bandes ne font pas des bulles.

Elles sont alors horizontales. Le graphique ci-dessus montre de fausses sorties. Souvent, après une grande bulle les cours se stabilisent et fluctuent dans un canal plus ou moins large. Alors que pendant la bulle de Bollinger, les acheteurs étaient largement gagnants, maintenant la lutte est plus acharnée entre les acheteurs et les vendeurs.

Sur le graphique ci-dessous cela se traduit par des mouvements désordonnés. On remarquera quand même un canal horizontal. Pour moi elles sont dues à un momentum force du mouvement trop faible moyennes mobiles longues sans pentes.

Squeeze et feinte de corps. Ils permettent de mettre en valeur certaines situations. On peut les utiliser dans des systèmes de trading automatisés car ils sont plus aisés à analyser via un programme informatique que les bandes de Bollinger. Cet indicateur donne la position en pourcentage du cours de clôture par rapport aux bandes de Bollinger.

Avec cet indicateur une fausse sortie se traduit par un pic ou un creux.
