In every market there are ebbs and flows. Some markets move very predictably as with the release of content patches and arena seasons. Others move sporadically with the availability of raw materials, which can (and often are) effected by a massive ban on bots. In all of these markets, some will find themselves to have steep peaks and massive declines, while others will stay relatively calm - with very slight growths and declines.
The key to maximizing your profits, and to protecting your liquidity, is to diversify. Diversity protects you as a Goblin in that it gives you wiggle room. As an example of this, I will use my own story.
When I re-started my career as a goblin, I used Inscription to spearhead my operation. In a matter of two weeks, I moved my liquidity from 2,000 to 8,000 gold - and then the MMO-Champion articles were released. Over the course of 3 days I went from earning 500g to 800g nightly to a meager 150g to 300g. I was fortunate at the time in that I have both a Jewelcrafter and an Enchanter - and so it was at that point that I began working the Saronite Shuffle.
If it hadn't been for my opportunity to diversify with some of the other professions that I had maxed out, I probably would have been run out of the market at that point. Since that shift, I have decided to bring down the Glyph market in order to weed people out while I continue to make profits elsewhere.
What I'm doing NowFortunately, with the capital I've earned from the Glyph market, I've been able to diversify into several areas.
Jewelcrafting & EnchantingI'm doing the usual Saronite Shuffle stuff with these two professions. I haven't bothered to look into the Enchant Scroll market yet - but that option is always open to me.
TailoringAbout a week and a half ago I brought my Tailoring up to 425, and basically sat on a stockpile of Netherweave Bolts made from cloth I bought on-the-cheap. It wasn't until late last week that I found out how fast Netherweave Bag's sell out (and usually in sets of 4). I'm still working on finding a cloth farmer to make this a bit more profitable, but otherwise it's a HOT market to be in if you can get cheap Netherweave. I also make the various "weaves" (Ebon, Spell, Moonshroud) for a nice chunk of change. I'm still slowly working toward being able to make the Spellthreads for some cash.
AlchemyTwo nights ago I maxed out my Alchemy, complete with Elixir Mastery. This week I'll be testing the waters on Flasks, and hopefully sometime soon Potions of Speed. Right now the profit on an individual Flask can be pretty marginal, but hopefully the mastery proc's will serve to make this more profitable.
InscriptionRight now I'm working on keeping this market's profit margins fairly low. I'm throwing 48 hour posts on the AH in stacks of two, with a "Smart Undercut" against my competition. I don't do ANY cancelling, so that my competition will continue to keep undercutting me for marginal profits.
One Last TipI suggest buying in BULK if you plan to work up a new profession on an alt. If someone catches wind that you are mass-buying items that look like you're power leveling a profession, their sure to buy the next item up and re-list it for exuberant prices. This happened the day after I broke 425 on Tailoring - and luckily, I wasn't buying much at that point.
