Can I plot momentum on the upper chart? and set an arrow up and down when it break 0?

[lguides]

def ml = 12;
plot Mom = price - price[ml];
def zline = 0;

plot mm1 = if Mom > zline then zline else double.nan;
mm1.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
mm1.SetDefaultColor(Color.GREEN);
mm1.SetLineWeight(4);
plot mm2 = if Mom < zline then zline else double.nan;
mm2.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
mm2.SetDefaultColor(Color.GREEN);
mm2.SetLineWeight(4);

Some very minor fixes, changs.

input ml = 12;
def Mom = close - close[ml];
plot mm1 = Mom > 0;
mm1.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
mm1.SetDefaultColor(Color.GREEN);
mm1.SetLineWeight(4);
plot mm2 = Mom < 0;
mm2.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
mm2.SetDefaultColor(Color.RED);
mm2.SetLineWeight(4);

I think it really doesn't work to have it on the upper chart, I hope there's an admin, moderator, or staff that can answer my question.

When creating plots in thinkscript you not only have to define the logic of what you want plotted but you must also state WHERE on the candle or line that you want it plotted. (IE the low, high, open, close, of the candle).
So an example syntax is if mycondition is true then low else double.Nan (print nothing)

input ml = 12;
def Mom = close - close[ml];
plot mm1 = if Mom > 0 then low else double.NaN;
mm1.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_up);
mm1.SetDefaultColor(Color.GREEN);
mm1.SetLineWeight(4);
plot mm2 = if Mom < 0 then high else double.NaN;;
mm2.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
mm2.SetDefaultColor(Color.RED);
mm2.SetLineWeight(4);

This script is now correct syntax-wise but is probably not what you want.

Just for future reference, it is not unusual for us to fix the 1st mistake we see and call it fixed. Especially if we are not in front of a computer to test. While I can provide guidance on simple fixes, I am not half as smart as @Joshua.

Oh believe me, I was not calling it fixed by any stretch of the imagination, perhaps just no longer totally broken.

Don't know why I am even doing this still, but I think what he wants is more similar to something like this:

declare lower;
input ml = 12;
plot Mom = close - close[ml];
plot zline = 0;
plot mm1 = if Mom crosses above zline then mom else double.nan;
mm1.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
mm1.SetDefaultColor(Color.GREEN);
mm1.SetLineWeight(4);
plot mm2 = if mom crosses below zline then mom else double.nan;
mm2.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
mm2.SetDefaultColor(Color.GREEN);
mm2.SetLineWeight(4);

I tried something like this but it doesn't works it flatten my candles

def ml = 12;
plot Mom = close - close[ml];

plot mm1 = if Mom crosses below 0 then close else double.nan;
mm1.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
mm1.SetDefaultColor(Color.GREEN);
mm1.SetLineWeight(4);
plot mm2 = if Mom crosses above 0 then close else double.nan;
mm2.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
mm2.SetDefaultColor(Color.GREEN);
mm2.SetLineWeight(4);

Uncheck "fit studies" in chart settings maybe, or try the lower study I posted.

plot mm2 = if mom crosses below zline then mom else double.nan;
mm2.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
mm2.SetDefaultColor(Color.GREEN);
mm2.SetLineWeight(4);

Not totally Josh I do appreciate it but as I have said above I want this to plot on the upper (chart or candlestick) not on lower because it was obviously possible when declaring it on lower.

Would you mind sharing your code doing that? that was exactly what I want. However, I believe that you used "> 0" instead of "crosses above/below" that's why arrows are placing all around. thanks @MerryDay I appreciate it!

This should be incredibly simple, the reason your candles are being squished in that other example is probably because your plotting "mom" on the upper chart with "fit studies" enabled in options. Change "plot mom" to "def mom" or uncheck that box.

Yes @Joshua it works now I already change it.

 

[codydog]

Not sure if this helps, but with squishness, I use this-

input offset = 5;
plot hiz = if zscore > z then high + offset * ticksize() else double.nan;
plot lowz = if zscore < -z then low - offset * ticksize() else double.nan;
