How to create a scanner

New comment
 
I know about coding and I am recently got into meta trader.
I would like to create a scanner/program that will scan for Breakout in all instrument  ( I am using icmarkets )

What kind of Breakout you might ask?
For now something simple

Trading the Break (adapted from dailyfx article)

  • Breakouts emanate from range-bound markets as new information pushes prices higher or lower.
  • These breaks can often be accompanied with increased volatility that can prove devastating
  • Risk-Reward ratios are of the upmost importance, so traders can mitigate the damage of false breakouts while maximizing the reward of successful entries.

Since future price movements are, in essence, unpredictable; identifying with and trading in the direction of the trend gives the trader the chance to jump on the side of any bias that may have been seen in the market. And if those biases (trends) are to continue, the trader can potentially make three, four, or five times the amount they put up to risk.

Unfortunately, trends don’t always exist. More common is the condition with which prices aren’t displaying some element of a bias; when prices move in a range-bound fashion for an extended period of time. And because there is a lack of a bias, knowing how to trade in these situations can be quite a bit more difficult. But traders have two choices: They can trade as if the range is going to continue, or they can trade the range in the expectation of a breakout of those range-bound prices.


Breakouts

When prices do break-out from a range, the movement can be fast, violent, and extremely large. Imagine a rubber band being pulled all the way back, until eventually it pops; that’s somewhat similar to what can happen when a breakout takes place.
Trading a breakout is not for the faint of heart. Often the breakout will come from a news event, or a data announcement, or some other reason that causes traders to push prices being the previously defined support and resistance levels.

It often takes more than one attempt to catch a breakout


It’s this extreme pickup in volatility that makes trading breakouts so difficult; as the accompanying price movements can swing dangerously in both directions, and there will be many instances in which support and/or resistance get broken, only to see prices reverse and move in the opposite direction. This is the dreaded ‘false breakout.’

Because of the heightened volatility around such events, and given the risk of false breakouts; traders often need to focus more heavily on risk and reward while being more aggressive: cutting losers even quicker while also looking for larger profit targets when they find themselves on the right side of the trade.

Probabilities

Traders will often assign a lower probability of success to breakout strategies because of the aforementioned reasons. If a trader thinks they can usually win 1 out of every two trend trades, they will often look to win 1 of every 4 breakout trades.

And because breakouts have a lower probability of success, traders need to adjust risk-reward ratios accordingly: Looking at even tighter stops, and even larger profit targets.

So, we’ve warned you against the risks of trading breakouts; a logical question that follows is often ‘why would anyone trade breakouts when there might be a trend somewhere that can be traded?’

Well, the beauty of the breakout is in the potential. When a breakout does work, the upside can potentially be huge (just like the downside is huge, but can be addressed or offset with tighter stops).

New trends often form from an initial breakout; and this is a very natural life-cycle in financial markets. Let’s look at an example to illustrate


How to Trade Breakouts

The key ingredient to trading a breakout is Support and/or Resistance. These levels that may see changes in order flow are the same prices that traders can look to enter upon breaks.

Pivot Points are an extremely common option for breakout traders. Traders can look to these price levels for potential breakout moves, while placing entry orders just outside of these prices so that once a pivot point yields to a price surge, the entry is initiated and the trader is in the position.

Another common option for trading breakouts is including the Price Channels indicator (often called ‘Donchian Channels,’ after famed breakout-trader Richard Donchian). Price Channels will show the highest high, and the lowest low over the past x periods (x being the number of candles input by the trader). When prices approach these levels, they may go on to make higher highs, or lower lows; and this is the essence of a breakout entry.

The same type of logic can be utilized around psychological whole numbers, or round levels like 1.3500 on EURUSD or .9000 on AUDUSD. These round-number price levels will often see a large number of stops or limits, and this can stop a trend dead in its tracks, at least temporarily. But when a subsequent approach towards that level takes place, the number of stops or limits may not be able to hold back the surge of selling (or buying in the case of an up-trend).

This leads to one of the more common ways of trading breakouts; incorporating price action and previous market movements into the analysis.

How to Trade a Descending Triangle

Talking Points

  • Triangle price patterns can be used in Forex trading to identify potential breakout setups
  • Descending triangles form when a rising trend line and a horizontal support line converge
  • Traders can look for the breakout from the descending triangle to signal the continuation of the AUDJPY down move.


===============

What is a Descending Triangle pattern?

A descending triangle pattern is consolidation price pattern composed of lower swing highs pushed lower by an established downtrend line converging with a horizontal support made up of a series of swing lows located in roughly the same area. Another name for the descending triangle is the right triangle pattern due to its similarity to the geometric shape of the same name. The height of the triangle meets the horizontal support at a 90 degree angle.

Usually, descending triangles form as profit taking by sellers is met with bargain hunting buyers. However, the buying pressure is mutted as higher lows are not made. A news release or economic announcement could be the catalyst required to push price out of this coil tilting the balance strongly in the seller's favor. Unlike its cousins, the symmetrical triangle and ascending triangle, the descending lacks significant bullish participation indicated by that lack of higher lows.



Taking a look at the current AUDJPY 4-hour chart, you can clearly see price action bound between a descending trend line that connects the 11/6 swing high of 94.15 to 11/12 swing high of 93.05. This swing high is a lower swing high than the 11/10 93.19 swing high showing the building strength in the downtrend. Current price action within the triangle is below the 200 simple moving average (SMA), a key indicator that traders use to determine bullishness or bearishness.

Traders will watch price action for a 4-hour candle close below support to confirm that there is follow through in a potential breakout. Stops can be placed near the middle of the triangle just above the 93.00 and 200 SMA. The height of the triangle is a little over 170 pips. By extending this height from the support level of a potential breakout zone, look for a possible target of 91.14. The profit target coincides with the lows seen back on October 2nd.

In summary, descending triangles can be an excellent way to rejoin a downtrend that clearly illustrates risk and reward. Price has a tendency to break form the descending triangle in a downward direction.
