Show Forex Bid/Ask Spread

[Mikeming]

Hi,
Is there a way to clearly show the exact bid-ask spread in Forex charts ?
I have the data set to 1/10 pip increments and can see the exact bid and ask prices,
but I want an indicator that shows the spread as a figure somewhere on the chart
so that I can see it with a quick glance and don't have to calculate it mentally.
I am using the FXCM data feed.
Thanks.

Hello Mikeming,

Yes, this is possible.

Are you wanting when there is a trade at the bid or ask like what shows on a chart or are you wanting the updates as is shown in the Chart Trader area?

If you want when there are trades, add a secondary ask series to the script and this will provide you with all of the ask historical and real-time data for when there are trades at the ask. (The bid will be the primary by default as Forex data does not have a true last price. The last price is actually the bid price)

Add(Instrument.FullName, BarsPeriod.Id, BarsPeriod.Value, MarketDataType.Ask);

If you want where there are updates even when there is no trade, then you will want to do this in OnMarketData and capture each ask or bid change.

How could you create a condition that says the spread must be <= 1 ticks in order to execute an order? Also would this be good for fx futures and stocks?

I am testing with this... but doesn't seem to be working correctly.

double Spread = Math.Abs (GetCurrentBid()-GetCurrentAsk());
{
Print(Spread.ToString());
}
if (Spread <= 1 * TickSize);
{
Print("Spread Less Than or Equal to 1");
}
if (Spread > 1* TickSize);
{
Print("Spread Greater Than 1");
}

Hi brucelevy,

Thanks for your post.

I converted it to ticks and worked with it an as integer:

int Spread = (int) Instrument.MasterInstrument.Round2TickSize(Math.Ab s (GetCurrentBid()-GetCurrentAsk())/TickSize);

if (Spread == 1)
{
Print ("Spread = 1");
}
else if (Spread > 1)
{
Print ("Spread = "+Spread);
}
