<i>"so, any words of wisdom, from those who are making the most of the volatility, would be most appreciated."</i>
Unless I'm reading wrong, the OP asked anyone who has success to share some advice. OP stated they currently trade the ER... where does it ask for advice specific to trading the ER? I don't see that.
My suggestion includes ER being part of the OP's current challenge. I found it easier to profit in ES than ER myself, after years of experience with the latter. The approach I use is not systematic, hence any symbol that moves on a chart gives similar signals.
As for market orders, they totally eliminate the constant issue of not being filled to the tick. Any emini trader has experienced many times the frustration of planning a trade, patiently awaiting a trade and setting their limit order where it seems prudent. Everything done according to plan.
Then the emini symbol (pick one) trades right to their price, sits right on that price for seconds or minutes and then reverses on a dime to spurt off as expected... with no fill on the order. All that time, effort and planning down the drain. Am I the only one here whom that has ever happened to on limit orders to enter?
Also, limit entry orders in the ER will never fill five contracts or more consistently. There will always be partial slippage on the orders in illiquid markets unless they are crappy signals that take a ton of heat. If you have any kind of precision on your entry signals, the ER will fill one - two contracts of five or more and whisk away from limit orders all the time. Been there, lived thru that for years.
Market orders for entry (and stop-market exit) totally eliminate that frustration. The few trades stopped out to the exact tick are greatly trumped by an equal or greater number of trades otherwise missed that profit big.

ER is fine... but no one should marry any symbol out of emotion. For all we know, the ER2 will have 1/2 its current range when ICE lists the big contract and mini side by side. Arbs may chop the former range to pieces while spreading both for the different strike values. Who knows?
If pressed, I could trade any of the five minis (S&P 400 included) and make money. But why not follow the path of least resistance. At this point in time, ES has equal to greater $$ range than all others and many times the liquidity of all. It seems that part of the OP's problem is spiky gyrations in ER... hence suggestion to look elsewhere and compare
