Trend, support and resistance

A level is not a line drawn by an authority. It is a price at which a large number of orders were filled in the past. Those fills left people with positions, and positions create future orders. When price returns to that area, some of those people act again.

Suppose USD/INR fell to 83.2000 three times in recent weeks and each time buyers stepped in. The buyers who missed the first move may have pending orders near 83.2000. The sellers who bought higher may want to exit near their entry. Both groups place orders around the same price without coordinating.

That is why the level looks like it works. It is a cluster of intentions, not a physical barrier. The cluster can be thin or thick. A level touched once on a quiet day carries less weight than one touched several times with wide daily ranges.

Nothing about the level tells you it will hold again. It tells you where attention is concentrated. Attention can produce a reaction, or it can produce a fast move through the level when the orders on one side run out.

Support is a level below the current price. Resistance is a level above it. The names describe where price is now, not a property of the line itself. When USD/INR trades at 83.2500, a level at 83.2000 is support and a level at 83.3000 is resistance.

If price breaks above 83.3000 and later falls back to it, the same line becomes support. Traders who sold at that level are now losing and may buy to close. That buying can slow the fall. The label changed because the price changed, not because the line did.

This is why drawing a level once and never revisiting it is a mistake. A level that mattered six months ago may have no orders left around it. A level formed last week may hold far more. The chart does not mark which is which.

You can test this yourself. Pick a level on USD/INR and count how many times price closed through it rather than turned at it. The count is often higher than a first glance suggests.

A level is an area, not a single number. On USD/INR, a support zone might run from 83.1950 to 83.2050. Price may dip to 83.1980, reverse, and never touch 83.2000 exactly. If you treat the exact number as the level, you will misread what happened.

Watch how price arrives. A slow drift into a level is different from a sharp spike. A spike often overshoots because orders are thin at that moment. A slow approach gives resting orders time to fill and can produce a steadier turn.

Watch what happens after the touch. If price leaves the level quickly and does not return, the reaction was strong. If price lingers and chops around the level, the orders are balanced and the next move is less clear. The behaviour after the touch carries more information than the touch itself.

Volume is not shown on every chart, and its meaning varies between brokers and platforms. Treat it as a clue, not a verdict. The same applies to any indicator built on top of price.
