Why does the API return different data to shown in the web app, with low prices not being lowest? [Solved... user error]


Guest DanT

Question

I was trying to write some algorithms using the API, but I keep finding instances where the data doesn't seem to add up (and is different to what's shown in the web app).

 

Here's one example where the lowPrice has a higher bid than the closePrice according to the API - however the low bid price shown in the web app is lower. The result is that I have candles where the wicks go inside the body (this happens if I draw using bid, or using mid points).

 

I can't figure out why the web app and the API would show different data (this isn't the only place, I've found several instances of this and I've barely done any checking!)..

IG have responded to a request regarding the unsatisfactory operations of their web trader platforms.

The web platform has known issues, i.e. it does not show the correct prices of the underlying market as the market prices change. If you are a trader who places a trade based on the ticket price, or the bar/candle chart, or the horizontal fill lines, be aware!! I have sent graphic shots of three different entry prices on the same chart at the same time depending on whether you are looking at the ticket, the bar or the entry order lines.

The response from IG is copied below:

Thanks for your email. There is already an investigation for the problem where sometimes the bid/ask price will fall outside of what is displayed on the charts, the reference number for it is INC0337629. It is a display problem which does not affect the execution of the trade, it also only seems to happen on the web platform so if you are unsure of the chart price then you can compare it to the chart price on the mobile app.

What is so surprising is that someone in a support role is so ignorant of trading. Any trader who manually enters a position or manages stops manually is at a distinct disadvantage with IG...of course your trade is affected if the price on the chart/bar is 6708 and you get filled at 6710 (when the spread is 1 point)..but of course you should know to have your phone app running at the same time to make sure your web price is at the real price !! Really, seriously?

My suggestion: Dont trade with IG. They have shown here they know they have an issue but are happy not to oblige their clients with refunds when their platform fills at wrong prices. 

You have been warned....

I never traded with real money here - I was disappointed enough with the demo system that I decided I just didn't trust it. I frequently ended up with trades that were open but not listed in the web app, or listed in the web app but actually closed (clearing cookies, app data, logging out/in did not help). Every time I contacted them they said this only happened on demo because it was "a simulated environment" and if it did ever happen on live (wait, I thought it couldn't?) I would be compensated. I wouldn't like to have that fight since it would be very difficult prove from screenshots what had occurred. With the stakes involved, it's critical customers can trust the platform, and I just didn't.

 

There were also other small annoying things, like having hugely different minimum bets between live/demo, which makes moving to live harder because you might find you can't do some of the things you were doing on demo on live (I did report this a few times, but it was never fixed before I gave up).

    • Gold Elliott Wave Analysis  Function - Trend Mode - Impulse Structure - Impulse wave Position -Wave 4 Direction - Wave 5 Details -  Wave 4 has reached the extreme area and bounced off the 2300 MG1. We will expect wave 5 to progress higher. However, it’s still in the early stages. Invalidation below 2245.17. Gold has undergone a retracement since its peak on April 12th, following a remarkable surge to a fresh all-time high. Despite this pullback, the underlying bullish momentum remains robust and is anticipated to reassert itself once the corrective phase concludes. In today's analysis, we delve into the potential areas where Gold may discover the necessary support to propel its next upward movements.   Zooming into the daily chart, our Elliott Wave analysis commences with identifying an impulse wave sequence originating from the low at 1614, marking the termination of wave (IV) at the supercycle degree back in September 2022. Presently, the supercycle wave V is unfolding, currently navigating through the third leg of the cycle degree, denoted as wave III. Within this wave III, classified as an impulse wave, we find ourselves within the third sub-wave, indicated as blue wave '3' of primary degree, further delineated into wave (3) of intermediate degree. Within this intricate structure, the price action appears to be nearing the culmination of minor degree wave 4. Consequently, the impulse sequence characterizing the intermediate wave (3) has yet to finalize, let alone the overarching supercycle wave (V). Thus, Gold's bullish trajectory remains firmly intact, advocating for a strategic approach of buying into the dips within this robust trend. Presently, the price appears to be undergoing a dip corresponding to wave 4 of (3), with an anticipated subsequent uptrend in wave 5.    Transitioning to the H4 chart, our focus narrows on the completion of wave 4, manifesting as a zigzag pattern since the peak on April 12th. Conventionally, the termination of the third leg of a zigzag typically occurs at extensions ranging from 100% to 138.2% of the initial leg's length from the subsequent corrective move. However, an extension beyond 138.2%, particularly to 161.8%, tends to invalidate the zigzag pattern. In this context, we cautiously assert that the zigzag for wave 4 might have concluded, with a critical level of invalidation identified at 2245. Nonetheless, further confirmation is sought through the emergence of more bullish candle formations. Meanwhile, the target projection for wave 5 remains at 2500, aligning with the continuation of Gold's upward trajectory within the Elliott Wave framework.

    • Surprising US PMI drops contrast with Europe’s gains in services, pushing EUR/USD higher as markets recalibrate economic outlooks and monetary policy expectations.   Source: Getty   Forex Euro Pound sterling European Union Inflation EUR/USD Written by: Richard Snow | Analyst, DailyFX, Johannesburg   Publication date: Wednesday 24 April 2024 07:28 Flash PMI data provides unflattering US outlook, Europe improves German and EU manufacturing remains depressed but encouraging rises in flash services PMI results suggest improvement in Europe. UK manufacturing slumped well into contraction, but also benefitted from another rise on the services front. It was the US that provided the most surprising numbers, witnessing a decline in services PMI and a drop into contractionary territory for manufacturing – weighing on the dollar. EUR/USD rises after us PMI shock EUR/USD responded to lackluster flash PMI data in the US by clawing back recent losses. The euro attempts to surpass the 1.0700 level after recovering from oversold territory around the swing low of 1.0600. The pair has maintained the longer-term downtrend reflective of the diverging monetary policy stances adopted by the ECB and the Fed. A strong labour market, robust growth and resurgent inflation has forced the Fed to delay its plans to cut interest rates which has strengthened the dollar against G7 currencies. The surprising US PMI data suggests the economy may not be as strong as initially anticipated and some frailties may be creeping in. However, it will take a lot more than one flash data point to reverse the narrative. If bulls take control from here, 1.07645 becomes the next upside level of interest followed by 1.0800 where the 200 SMA resides. On the downside, 1.06437 and 1.0600 remain support levels of interest if the longer-term trend is to continue. EUR/USD daily chart     Source: TradingView EUR/GBP surrenders recent gains EUR/GBP rose uncharacteristically on Friday when risks of a broader conflict between Israel and Iran subsided. In addition, the Bank of England’s(BoE) Deputy Governor Dave Ramsden stated that he sees inflation falling sharply towards target in the coming months, sending a dovish signal to the market. Today the BoE’s chief Economist Huw Pill tried to walk back such sentiment, stressing that the bank needs to maintain restrictiveness in its policy stance. He did however, echo Ramsden’s remarks by saying the committee is seeing signs of a downward shift in the persistent component of the inflation dynamic. EUR/GBP appears to have found resistance around 0.8625 and has traded lower after the PMI data, even heading lower than the 200 SMA. A return to former channel resistance is potentially on the cards at 0.8578. Prices settled into the trading range as central bankers mulled incoming data and the prospect of a first rate cut appeared a fair distance away. Longer-term, the ECB is on track to cut rates in June, meaning sterling will extend its interest rate superiority and is likely to see the pair test familiar levels of support.
