Why I put a live spread readout on my chart and what it stopped me doing

a small change that saved me a lot of silly entries was adding a spread indicator to the corner of the chart. It shows the current spread in pips, and I set it to change color when it's more than a certain multiple of what's normal for that pair.

Before I did this, I'd enter a trade without noticing the spread was wide. The setup looked right and the stop was in the right place, but I'd started in a hole. With the readout, I can see at a glance and I just don't enter if it's red.

I also noticed patterns I hadn't paid attention to. The spread jumps at certain times, like right at the session open, near rollover and in the first moments after news. It also tends to be wider on certain pairs at certain hours. Seeing it on the screen all day made it a part of my decision, not an afterthought.

If your platform doesn't have one built in, there are free ones for it, or you can look at the market watch window with the spread column. The point is that the spread should be visible when you click.

How I decided what counts as normal for each pair. I watched the spread readout for a couple of weeks and wrote down what it showed during my usual trading hours on quiet moments. That became my baseline. I set the colour change to about one and a half times that number. It is not exact, but it catches the obvious cases where the spread has doubled or tripled, which are the ones that really hurt a scalp. You can tweak the multiple later once you have a feel for each pair.

Another thing the readout made obvious is how much the spread affects where my stop really is. If my stop is five pips away and the spread is one pip, that is a big chunk of the risk before price even moves. When I saw that clearly, I stopped taking setups that needed very tight stops during wider spread periods. The setup looked identical, but the real risk was quite different. Now I either wait for the spread to calm down or use a setup with a wider stop and a smaller size, so the cost is a smaller share of the trade.

Showing the ask price as a line is a good companion to the readout. Candles are drawn from the bid, so a buy stop just above a high triggers on the ask, and with a 2 pip spread it can fill while the candles never seem to touch the level.

A single baseline per pair might be too blunt, since normal is different at different hours. A spread of 1.5 pips on EURUSD would be a clear red flag at 9 in the morning in London and fairly ordinary in the last hour before rollover.

Tying the colour to the stop instead of to the usual spread is another way to set it. Say the rule turns red once the spread is more than a tenth of the planned stop, so a 0.6 pip spread is fine on a 10 pip stop and too much on a 4 pip one.

That version follows directly from the point above about the spread being a chunk of the risk. It also adjusts by itself when a setup with a wider stop is chosen for a busy period.

Does the readout update only on new ticks? In a quiet moment it can keep showing the last value for a while, which might be the wide one from a minute earlier.

Rollover is where the readout earns its place, and its timing is about to move. The 5pm New York daily close is 10pm in Lagos until US clocks change on Sunday 1 November, then 11pm from Monday 2 November.

Say EURUSD normally shows 0.6 pips in the morning, so the one and a half times rule turns the readout red at 0.9. On a made up but typical day it stays green from the London open into the New York afternoon, turns red in the thin hour before rollover and jumps to around 2.5 pips just after it.

The chart (illustration) plots that day hour by hour in Lagos time, with the 0.9 line marked. The red stretch through Asia is mild, while the spike after the close is the one that matters for open trades.

Rollover spreads can briefly reach several pips, and a long's stop triggers on the bid even if the mid price barely moves. Closing before that hour, or a wider stop with smaller size, avoids being stopped by the spread alone.

Is the readout showing the spread at the latest tick, or the widest one in the last minute? A rolling maximum over 60 seconds catches the brief spikes that a single value can miss between glances.

A live spread indicator is one of the simplest and most effective tools for scalpers. The colour change is a nice touch, because a number alone is easy to ignore when you are focused on the chart.

It might be worth logging how many trades the indicator stopped you from taking, and what those trades would have done. If the skipped trades would have lost money after the wider spread, it shows the value of the tool very clearly.
