Trading session OHLC indicator

[Fredo]

Good day fellow traders,

I have recently gone minimalist on my charts and trying to trade only the open price of each trading session. I'm not getting rich yet, but I have an edge and I like it that way.

I'm using the TRO_OHLCLines indicator for every trading session and only leave the Open price visible.

Now, I have a very simple request. Could someone help me out to draw lines at 3 Pips over and under the open price automagically?

I've also fiddled with TRO_TRADE_LINES_ohlm with which I was able to plot the +3, -3 Pips, but unfortunately cannot make it work on more than the daily open price.
