PMF (Power Momentum Formula) for ThinkorSwim

[isaacramsay]

Here is the Power Momentum Formula, a Momentum Divergence study/strategy. So far, it checks for the high/low over the last 60 bars, and if the Momentum(28) is not a high/low to go along with the price high/low and they're more than 6 bars apart, then lines are drawn. It still needs a little work, and I still have to add the trigger point (trade entry) conditions with alerts and potential profit ranges, then make it into a strategy.

Any chance you can confirm the delay and if you have made any adjustments to this indicator since posting? Seems to work well once triggered. Im just wondering how long until confirmation bar is plotted.

Thank you in advance!

 

[tride]

Thanks for sharing, curios if you were able to make further progress on the strategy?

Hey isaac I'm new to trading for about 2 months now and I love your indicator. Its pin point accurate. However I am alittle concerned I think there may be a broken code written somewhere within it. When I try to use it in live virtual trading, it makes the price action chart not move. Like the bars with go up and down but it wont show a trend across the screen like it normally those. Only when I take it off will the chart move again. So I've been using it when i think there could be a possible divergence i would install the script to see where then uninstall it when I'm not using it. Could you please please fix it. I really love this indicator.....thank you so much

It don't work properly in on-demand so I'm having to install and uninstall when I need to use it and when I dont

@craig81 There are several indicators or setups that don't play well with OnDemand... Renko Bars and Range Bars just freeze after a few seconds, if they work at all, and some MTF indicators... Everything is hit and miss with OnDemand... I tried it again last week and gave up within a few minutes...

 

[craig81]

Seems to work without on demand but I cant practice with it.

 

[rad14733]

Seems to work without on demand but I cant practice with it.

You could use PaperTrading during trading hours... I have a second install of TOS that I use if I really want to test but it still isn't like live trading...

 

[alexR]

@isaacramsay Interesting, would love to see final result.

 

[autoloader]

It looks very interesting but the lower doesn't actually operate as a lower. It draws in the upper chart area.

 

[tradegeek]

@autoloader

I think you have to delete

declare upper;

and place

declare lower;

at the very top of the lower study.

 

[rad14733]

You can also drag Upper indicators into the Lower section OR drag Lower indicators into the Upper section...
